The flaw, which surfaced last week as a zero-day attack against Windows systems, allows remote code execution via rigged Flash files.
According to Adobe, the vulnerability affects Adobe Flash Player 10.1.82.76 and earlier versions for Windows, Macintosh, Linux and Solaris. It also affects Flash Player 10.1.92.10 for Android.
This vulnerability (CVE-2010-2884) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being actively exploited in the wild against Adobe Flash Player on Windows.
