Jose A. Vazquez a security researcher recently disclosed a critical security flaw within the Opera Web-browser, which if exploited, could allow the injection of malware, stated esecurityplanet.com dated October 17, 2011.
Actually according to Vazquez, the flaw was first discovered in 2010 following which he soon informed the browser's creators while providing a POC (proof-of-concept). Nevertheless, he adds that Opera thought it okay to leave the flaw un-patched. H-online.com reported this on October 17, 2011.
Furthermore, as per Vazquez, Opera's creators probably tested the 10.6 exploit version he provided on the latest 11.x edition that may've resulted in the exploit's breakdown. Thereafter, rather than again contact Opera, Vazquez recently made a design for the exploit to adapt it to Opera's latest 11.51 edition, while publishing it like a Metasploit program, meaning that essentially anybody is now capable of abusing the flaw.
