Red Hat Inc Announced The General Availability Red Hat Enterprise Linux (RHEL) 6.5

Posted by Avik Sarkar On 11/30/2013 03:32:00 am

Red Hat Inc Announced The General Availability Red Hat Enterprise Linux (RHEL) 6.5 

The RHEL 6x series get another important update as Red Hat Inc, the world's leading provider of open source solutions announced the general availability of Red Hat Enterprise Linux 6.5, the latest version of Red Hat Enterprise Linux 6. According to the official press release of Red Hat -RHEL 6.5 expands Red Hat’s vision of providing an enterprise platform that has the stability to free IT to take on major infrastructure challenges and the flexibility to handle future requirements, with an extensive partner and support ecosystem. 
Red Hat Enterprise Linux 6.5 is mainly designed for those who build and manage large, complex IT projects, especially enterprises that require an open hybrid cloud. From security and networking to virtualization, Red Hat Enterprise Linux 6.5 provides the capabilities needed to manage these environments, such as tools that aid in quickly tuning the system to run SAP applications based on published best practices from SAP.“Red Hat Enterprise Linux 6.5 provides the innovation expected from the industry’s leading enterprise Linux operating system while also delivering a mature platform for business operations, be it standardizing operating environments or supporting critical applications. The newest version of Red Hat Enterprise Linux 6 forms the building blocks of the entire Red Hat portfolio, including OpenShift and OpenStack, making it a perfect foundation for enterprises looking to explore the open hybrid cloud.”-said Jim Totton, vice president and general manager of Red Hat Inc. Now lets take a closer look to the main highlights of RHEL 6.5 : 

Securing the Next-Generation Enterprise
Red Hat Enterprise Linux 6.5 continues the push for integrated security functionality that combines ease-of-use and up-to-date security standards into the platform. The addition of a centralized certificate trust store enables standardized certificate access for security services. Also included are tools that meet leading security standards, including OpenSCAP 2.1, which implements the National Institute of Standards and Technology’s (NIST’s) Security Content Automation Protocol (SCAP) 1.2 standard. With these additions, Red Hat Enterprise Linux 6 provides a secure platform upon which to build mission-critical services and applications.

Networking – When Every (Micro)Second Matters
In the financial services and trading-related industries, application latency is measured in microseconds, not seconds. Now, the latest version of Red Hat Enterprise Linux 6 fully supports sub-microsecond clock accuracy over the local area network (LAN) using the Precision Time Protocol (PTP). Precision time synchronization is a key enabler for delivering better performance for high-speed, low latency applications. Red Hat Enterprise Linux 6.5 can now be used to track time on trading transactions, improving time stamp accuracy on archived data or precisely synchronizing time locally or globally. Thanks to other networking enhancements in Red Hat Enterprise Linux 6.5, system administrators now have a more comprehensive view of network activity. These new capabilities enable sysadmins to inspect IGMP (Internet Group Management Protocol) data to list multicast router ports, multicast groups with active subscribers and their associated interfaces, all of which are important to many modern networking scenarios, including streaming media.

Virtualization Enhancements
Red Hat Enterprise Linux 6.5 continues Red Hat’s commitment to improving the overall virtualization experience and includes several improvements that make it a compelling choice for running in virtualized environments. Sysadmins can now dynamically enable or disable virtual processors (vCPUs) in active guests, making it an ideal choice for elastic workloads. The handling of memory intensive applications as Red Hat Enterprise Linux guests has also been improved, with configurations supported for up to 4TB of memory on the Kernel-based Virtual Machine (KVM) hypervisor. The KVM hypervisor also integrates with GlusterFS volumes to provide direct access to the distributed storage platform, improving performance when accessing Red Hat Storage or GlusterFS volumes. Finally, guest drivers have been updated to improve performance of Red Hat Enterprise Linux 6.5 running as a guest on supported third-party hypervisors.

Evolving Ease-of-Use, Storage, and More
As application deployment options grow, portability becomes increasingly important. Red Hat Enterprise Linux 6.5 enables customers to deploy application images in containers created using Docker in their environment of choice: physical, virtual, or cloud. Docker is an open source project to package and run lightweight, self-sufficient containers; containers save developers time by eliminating integration and infrastructure design tasks. Red Hat Enterprise Linux 6.5 stays current with the advancements in Solid-State Drive (SSD) controller interface, introducing support for NVM Express (NVMe)-based SSDs. The NVMe specification aims to standardize the interface for PCIe-based SSDs and its inclusion in Red Hat Enterprise Linux 6.5 positions the platform to support an expanding range of future NVMe-based devices.

Improvements have also been added to improve enterprise storage scalability within Red Hat Enterprise Linux 6.5. It is now possible to configure more than 255 LUNs connected to a single iSCSI target. In addition, control and recovery from SAN for iSCSI and Fibre Channel has been enhanced, and updates to the kexec/kdump mechanism now make it possible to create debug (dump) files on systems configured with very large memory (e.g. 6TB).

Red Hat Enterprise Linux 6.5 makes it easier to track and manage subscription consumption across the enterprise, integrating subscription tracking into existing business workflow. Usability enhancements include support for remote access to Windows clients and servers that use a newer version of the RDP protocol, including Windows 7 and 8 desktops and Windows Server 2012.

Posted by Avik Sarkar On 11/17/2013 06:32:00 pm

Apple Brings iOS 7.0.4 & iOS 6.1.5 Includes New Features, FaceTime Bug  & App Store Purchase Flaw Fixed


California based tech giant Apple Inc has released a new update on their popular iOS software running on iPhone, iPad, and iPod touch devices. This release of of iOS 7.0.4  includes bug fixes and improvements, including a fix for an issue that causes FaceTime calls to fail for some users. iPods that are not able to upgrade to iOS 7 have their own version to upgrade to, iOS 6.1.5. The release of iOS 7.04 marks the third update of the iPhone operating system in the short time since Apple pushed out iOS 7 in September. The new OS represented a major change from the older operating systems, both in the look and feel of the software and in its functionality.  There’s much zooming in and out and all about in iOS 7, as well as a blurry background that has drawn quite a bit of criticism. iOS 7 also was a major security release, fixing issues with the iPhone’s certificate trust policy as well as remote code-execution vulnerabilities in the CoreGraphics and CoreMedia components. 

The new update improves iCloud Keychain, which was introduced in iOS 7.0.3, and the latest version of the desktop software, OS X Mavericks. The cloud-based technology keeps the Safari browser's passwords and credit card data in sync across all your Apple devices. Secondly, in Spotlight, the device's internal search engine, Apple has brought back the ability to search Google and Wikipedia from the results. The two services were removed when iOS 7 was first released in mid-September. 
Also on Thursday, Apple released a corresponding update to its Apple TV, updating the set-top box to version 6.0.2.  Users can update to the latest version by accessing the device's Settings, selecting General, then Software Update. In spite of the relatively small size of the update, it's recommended that users use Wi-Fi when updating. To avoid security vulnerabilities every Apple users are highly recommended to update their software.

42 Java Holes Fixed By Oracle in April 2013 Critical Patch Update Advisory

Posted by Avik Sarkar On 4/18/2013 06:08:00 pm

42 Java Holes Fixed By Oracle in April 2013 Critical Patch Update (CPU) Advisory

The Oracle Corporation has released what it called a critical patch update for its Web-based Java programming language. Java SE software that fixes at least 42 security flaws in the widely-installed program and associated browser plugin. The Java update also introduces new features designed to alert users about the security risks of running certain Java content. The April patch, which targets 42 vulnerabilities, 19 of which have a severity rating of 10 (highest possible threat level) includes a majority of vulnerabilities that are currently being exploited. Among those 42 new security fixes across Java SE products of which 2 are applicable to server deployments of Java.  According to Oracle, “39 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without the need for a username and password.” Along with the fixes, Oracle changed the default setting of Java SE. Java applets will no longer run in a Web browser unless they have been digitally signed until a warning prompt is acknowledged. It has also extended how users will be alerted of other Java-related security issues. According to renowned security expert and blogger Brian Krebs - Java 7 Update 21 also introduces some new security warnings and message prompts for users who keep the program plugged into a Web browser (on installation and updating, Java adds itself as an active browser plugin). Oracle said the messages that will be presented depend upon different risk factors, such as using old versions of Java or running applet code that is not signed from a trusted Certificate Authority. Apps that present a lower risk display a simple informational message. This includes an option to prevent showing similar messages for apps from the same publisher in the future. Java applications considered to be higher risk — such as those that use an untrusted or expired certificate — will be accompanied by a prompt with a yellow exclamation point in a yellow warning triangle.

Affected Product Releases and Versions:-
Java SEPatch Availability
JDK and JRE 7 Update 17 and earlierJava SE
JDK and JRE 6 Update 43 and earlierJava SE
JDK and JRE 5.0 Update 41 and earlierJava SE
JavaFX 2.2.7 and earlierJavaFX
Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply CPU fixes as soon as possible. As Java has been run by millions of devices and users across the globe, so we urge all of our readers to install and apply the security fixes to avoid any kind of threats. Note that - Oracle said that this week's security updates don't take care of all known flaws, they do address all known vulnerabilities currently being exploited in the wild.

PostgreSQL Fixed “Persistent Denial-of-Service” Vulnerability (CVE-2013-1899)

Posted by Avik Sarkar On 4/11/2013 01:44:00 am

PostgreSQL Fixed 'High-Exposure Security Vulnerability' Causing Denial-of-Service Attack (CVE-2013-1899)

Security researcher's have yet again figured out a serious security hole in one of most widely used object-relational database management system, PostgreSQL also known as Postgres. While manipulating the loophole an attacker can easily corrupt files and in some cases, can execute malicious code on underlying servers causing "persistent denial-of-service" attack. By corrupting the files an attacker can cause database server to crash and refuse to reboot. Affected servers could only be restarted by removing garbage text from the files or by restoring them from a backup. Versions 9.0, 9.1, and 9.2 are all vulnerable. As soon as this vulnerability get spotted, the developers at PostgreSQL immediately  released updates while addressing a "high-exposure security vulnerability in versions 9.0 and later." The updates are available for 9.0, 9.1, and 9.2 branches, as well as 8.4. This updates also allow PostgreSQL to be built using Microsoft Visual Studio 2012. According to developers: "A major security issue fixed in this release, CVE-2013-1899, makes it possible for a connection request containing a database name that begins with "-" to be crafted that can damage or destroy files within a server's data directory. Anyone with access to the port the PostgreSQL server listens on can initiate this request. This issue was discovered by Mitsumasa Kondo and Kyotaro Horiguchi of NTT Open Source Software Center." In addition to fixes for one major security issue, the updates also include four more minor security fixes, as well as fixes for other, non-security-related issues. 

Some of these fixes include:
  • A security vulnerability that made contrib/pgcrypto-generated strings too easy to guess;
  • A vulnerability that would allow unprivileged users to interfere with backups;
  • Security issues involving the OS X and Linux installers;
  • Vaious issues with GiST indices;
  • An issue related to crash recovery; and
  • Memory and buffer leaks, among others.

The complete list of fixes and enhancements in each version can be found on the PostgreSQL release notes archive page. Also the patched PostgreSQL 9.2.4, 9.1.9, 9.0.13, and 8.4.17 are available now at download  page. While talking about this fix, we would like to remind you that, late in last year another security vulnerability hit PostgreSQL database system, including versions 9.1.5, 9.0.9, 8.4.13 and 8.3.20. The security holes associated with libxml2 and libxslt. Along with that a vulnerability in the built-in XML functionality, and a vulnerability in the XSLT functionality supplied by the optional XML2 extension.

'Kali Linux' The Most Advanced & Stable Penetration Testing Distribution

Posted by Avik Sarkar On 3/15/2013 12:49:00 am

From The Makers of BackTrack We Got 'Kali Linux' The Most Advanced & Stable Penetration Testing Distribution 

Fans of world famous penetration testing distribution 'BackTrack' can now taste another flavor as the developer at BackTrack and Offensive Security has introduced a new Linux distribution targets enterprise security, offering a suite of helpful tools for rigorous testing calling it "Kali Linux." In the official release note Offensive-Security claimed that Kali Linux is the most advanced, robust, and stable penetration testing distribution to date. From that note we also came to know that this new distribution is a product of seven years long knowledge and experience which make Kali Linux the “next generation” penetration testing distribution. Now lets look at the main features of Kali Linux at a glance: 

Kali Linux Features:-

Kali is a complete re-build of BackTrack Linux, adhering completely to Debian development standards. All-new infrastructure has been put in place, all tools were reviewed and packaged, and we use Git for our VCS.
  • More than 300 penetration testing tools: After reviewing every tool that was included in BackTrack, we eliminated a great number of tools that either did not work or had other tools available that provided similar functionality.
  • Free and always will be: Kali Linux, like its predecessor, is completely free and always will be. You will never, ever have to pay for Kali Linux.
  • Open source Git tree: We are huge proponents of open source software and ourdevelopment tree is available for all to see and all sources are available for those who wish to tweak and rebuild packages.
  • FHS compliant: Kali has been developed to adhere to the Filesystem Hierarchy Standard, allowing all Linux users to easily locate binaries, support files, libraries, etc.
  • Vast wireless device support: We have built Kali Linux to support as many wireless devices as we possibly can, allowing it to run properly on a wide variety of hardware and making it compatible with numerous USB and other wireless devices.
  • Custom kernel patched for injection: As penetration testers, the development team often needs to do wireless assessments so our kernel has the latest injection patches included.
  • Secure development environment: The Kali Linux team is made up of a small group of trusted individuals who can only commit packages and interact with the repositories while using multiple secure protocols.
  • GPG signed packages and repos: All Kali packages are signed by each individual developer when they are built and committed and the repositories subsequently sign the packages as well.
  • Multi-language: Although pentesting tools tend to be written in English, we have ensured that Kali has true multilingual support, allowing more users to operate in their native language and locate the tools they need for the job.
  • Completely customizable: We completely understand that not everyone will agree with our design decisions so we have made it as easy as possible for our more adventurous users tocustomize Kali Linux to their liking, all the way down to the kernel.
  • ARMEL and ARMHF support: Since ARM-based systems are becoming more and more prevalent and inexpensive, we knew that Kali’s ARM support would need to be as robust as we could manage, resulting in working installations for both ARMEL and ARMHF systems. Kali Linux has ARM repositories integrated with the mainline distribution so tools for ARM will be updated in conjunction with the rest of the distribution. Kali is currently available for the following ARM devices:
Kali is specifically tailored to penetration testing and therefore, all documentation on this site assumes prior knowledge of the Linux operating system. For more information, I would like to request you to visit the official website of Kali Linux.

DHS & US-CERT Recommended to Disable Java in Web Browsers

Posted by Avik Sarkar On 1/18/2013 06:49:00 pm

DHS & US-CERT Recommended to Disable Java in Web Browsers Unless It's Absolutely Necessary

The running time is proving to be the worst period for Java, as it has been walking under serious security issues. Yet again security researchers have pointed out a zero-day security vulnerability in the Java program that hackers are exploiting. The exploit takes advantage of a vulnerability left open in Java 7 Update 10, released in October last year. It works by getting Java users to visit a website with malicious code that takes advantage of a security gap to take control of users' computers. Thus how Java is being used by cyber criminals to infect computers with malware. Oracle, hasn't specified the number of users who have downloaded Java 7 Update 10. However, Java runs on more than 850 million computers and other devices. When Oracle released Update 10, so it is predictable that more than 850 million devices run by Java is under threat. The exploit was first discovered by French researcher Kafeine, who claimed to have found it running on a site registering hundreds of thousands of page views daily. From that site, immediately that vulnerability and a large number of effected devices has been spotted in the wild. In Java 7 Update 10 the creator of Java, Oracle added several security control and fixed older bugs and promised more security enhancement, but its very unfortunate that Oracle failed to keep their promise. What ever after this newly discovered 0-day hole spotted wildly, Oracle Security Alert CVE-2013-0422 states that Java 7 Update 11 addresses this (CVE-2013-0422) and an equally severe, but distinct vulnerability (CVE-2012-3174). Immunity has indicated that only the reflection vulnerability has been fixed and that the JMX MBean vulnerability remains. Java 7u11 sets the default Java security settings to "High" so that users will be prompted before running unsigned or self-signed Java applets. It "strongly recommends" that Java SE 7 users upgrade immediately to avoid all kind of security hazards. 

After seeing all the drama, many of you have failed to keep trust in Java, and you all will be relieved when you will gone through the security advisory of CERT (Computer Emergency Response Team) where they have clearly instructed to disable Java in your popular web-browser. In their official release CERT said "Unless it is absolutely necessary to run Java in web browsers, disable it as described below, even after updating to 7u11. This will help mitigate other Java vulnerabilities that may be discovered in the future."

You will see similar advice in the advisory posted on the official DHS US-CERT website where DHS also suggested to disable Java until and unless it is that much necessary. "To defend against this and future Java vulnerabilities, consider disabling Java in web browsers until adequate updates are available. As with any software, unnecessary features should be disabled or removed as appropriate for your environment." - said U.S. CERT in their advisory.

SQL Injection Vulnerability Affected All Versions of Ruby on Rails

Posted by Avik Sarkar On 1/07/2013 06:19:00 pm

SQL Injection Vulnerability Affected All Versions of Ruby on Rails (CVE-2012-5664)

Developers at Ruby on Rails are warning its users regarding a Sql Injection flaws which has affected all the current version of Ruby on Rails web framework. While exploiting the vulnerability an attacker can inject and even execute malicious codes into the web application. "Due to the way dynamic finders in Active Record extract options from method parameters, a method parameter can mistakenly be used as a scope. Carefully crafted requests can use the scope to inject arbitrary SQL," explained the Rails framework's developers. As soon as this vulnerability has been spotted in the wild, the maintainers of Ruby on Rails have released new versions that addresses the flaw, versions 3.2.10, 3.1.9 and 3.0.18. In their advisory Ruby on Rails team recommends that users running affected versions, which is essentially anyone using Ruby on Rails, upgrade immediately to one of the fixed versions mentioned earlier. "We're sorry to drop a release like this so close to the holidays but regrettably the exploit has already been publicly disclosed and we don't feel we can delay the release," Rails developer concluded. 

The original problem was disclosed on the Phenoelit blog in late December where the author applied the technique to extract user credentials from a Ruby on Rails system, circumventing the authlogic authentication framework. While talking about the vulnerability discloser of Ruby on Rails, we would like to remind you that, this is not the first time, earlier in 2012 a Russian security researcher named Homakov has found that Github has succumbed to a public key vulnerability in Ruby on Rails which is allowing a normal user to gain administrator access into the popular Rails Git.

Brief About Ruby on Rails:- Ruby on Rails, often shortened to Rails, is an open source full-stack web application framework for the Ruby programming language. Ruby on Rails runs on the general-purpose programming language Ruby, which predates it by more than a decade. Rails is a full-stack framework, meaning that it gives the web developer the ability to gather information from the web server, talk to or query the database, and render templates out of the box. As a result, Rails features a routing system that is independent of the web server. Ruby on Rails emphasizes the use of well-known software engineering patterns and principles, such as Active record pattern, Convention over Configuration, Don't Repeat Yourself and Model-View-Controller.

Microsoft Security Advisory (2794220) Remote Code Execution Vulnerability in Internet Explorer Fixed

Posted by Avik Sarkar On 1/05/2013 09:48:00 pm

Microsoft Security Advisory (2794220) Remote Code Execution Vulnerability in Internet Explorer Fixed

The Redmond based software giant Microsoft issued an urgent security advisory to address vulnerabilities in its popular web-browser that is Internet Explorer.  Few of days new “zero day” security hole in IE was discovered which could potentially allow hackers to take over control of your system when all you've done is visit an infected website. The vulnerability affects IE versions 6, 7 and 8. Though the latest versions of the browser, that means IE 9 and 10, are not affected. “An attacker who successfully exploited this vulnerability could gain the same user rights as the current user.” Microsoft said in its statement. The statement went on to say, “an attacker could host a website that contains a webpage that is used to exploit this vulnerability. In addition, compromised websites and websites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability.”
On its advisory Microsoft first issued warning of the problem, which involves how IE accesses "an object in memory that has been deleted or has not been properly allocated." The problem corrupts the browser's memory, allowing attackers to execute their own code. Security vendor Symantec described such a scenario as a "watering hole" attack, where victims are profiled and then lured to the malicious site. Last week, one of the websites discovered to have been rigged to delivered an attack was that of the Council on Foreign Relations, a renowned foreign policy think tank. 
While talking about IE and its bugs, then we would like to remind you that couple of weeks ago, Spider.io a website analytics firm has discovered a security vulnerability in all current versions of Internet Explorer that allows attackers to trace mouse cursors anywhere on users' screens even if the Internet Explorer window is minimized. That time the software giant ignored that particular issue. But here they take this one bit seriously; So if you still using the older and affected version of IE, then its time to update your browser, in order to stay safe and secure on the Internet.
