Zero-Day Vulnerability in Opera Browser Found By Vázquez

José A. Vázquez, Security expert has released the details of a critical security hole in the Opera browser which can be exploited to inject malicious code. He says that he found the hole and notified the developers with a proof of concept a year ago. However, the expert said that Opera decided not to close the hole.
Vázquez thinks that the Opera developers might have tested his version 10.6 exploit with the current version 11.x, which may have caused the exploit to malfunction. Instead of contacting Opera again, Vázquez has adapted the exploit for the current version 11.51 of Opera and has released it as a Metasploit module. This means that, in principle, anyone can now exploit the vulnerability.

The hole is caused by a memory flaw when processing SVG content within framesets. Simply visiting a compromised web page is enough for a system to become infected with malicious code. Vazquez said that the exploit is successful in 3 out of 10 cases. With the pre-alpha version of Opera 12, the exploit managed to inject malicious code in 6 out of 10 cases.
Vázquez released a the 0day Exploit of Opera Browser 10,11 & 12. You can download that by clicking the following link.
By releasing the exploit, the security expert is forcing the browser developers into action. Later Opera respond and released a security update.
