Adobe has issued a security bulletin about a critical security flaw found in Adobe Flash Player affecting the Windows, Macintosh, Linux, Solaris, and Android operating systems. The vulnerability, labeled CVE-2011-0609, “could cause a crash and potentially allow an attacker to take control of the affected system.” The company reports that exploits are already in the wild — most prevalently attached to Flash (.swf) and Excel (.xls) files. Adobe notes that it is “aware” of exploits for Adobe Reader and Acrobat, but explains that “Adobe Reader X Protected Mode mitigations would prevent an exploit of this kind from executing.” The company has stated that it will issue a patch for its Flash Player sometime during the week of March 21st. Curiously, the company writes, “Because Adobe Reader X Protected Mode would prevent an exploit of this kind from executing, we are currently planning to address this issue in Adobe Reader X for Windows with the next quarterly security update for Adobe Reader, currently scheduled for June 14, 2011.” June? Wow. Now might be a good time to enable Protected Mode on Adobe’s PDF reader.
