Adobe said it discovered a critical vulnerability in Adobe Flash Player that could cause a crash and potentially allow an attacker to take control of the affected system. Reports have already surfaced that the security flaw is being exploited in the wild in targeted attacks through a Flash (.swf) file embedded in a Microsoft Excel (.xls) file delivered as an email attachment. A fix is on the way, but it won't arrive until next week Adobe says.
"We are in the process of finalizing a fix for the issue and expect to make available an update for Flash Player 10.x and earlier versions for Windows, Macintosh, Linux, Solaris and Android, and an update for Adobe Acrobat X (10.0.1) and earlier 10.x and 9.x versions for Windows and Macintosh, Adobe Reader X (10.0.1) for Macintosh, and Adobe Reader 9.4.2 and earlier 9.x versions during the week of March 21, 2011," Adobe said . "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."
The vulnerability exists is Adobe Flash Player 10.5.152.33 and earlier versions for all major platforms, including Windows, Max, Linux, and Solaris, as well as Android devices running 10.1.106.16 and earlier.
