Adobe is planning to release the fix for a critical vulnerability that affected certain versions of its flash player during the week of March 21, 2011.
Adobe rated the bug as critical, which, if exploited would allow malicious native-code to execute, potentially without a user being aware. In other words, the bug could cause a crash and potentially allow an attacker to take control of the affected system.
Hackers have exploited the bug in flash player using Microsoft Excel documents. They targeted users via a Flash (.swf) file embedded in a Microsoft Excel (.xls) file delivered as an email attachment.
The vulnerability exists in certain versions of Adobe Flash Player for Windows, Macintosh, Linux and Solaris operating systems, Adobe said in its blog post.
The bug also affected authplay.dll component that ships with Adobe Reader and Acrobat X (10.0.1) and earlier 10.x and 9.x versions for Windows and Macintosh operating systems.
