iDefense Security Advisory 02.08.11 - Remote exploitation of a memory corruption vulnerability in Adobe Systems Inc.'s Flash Player could allow an attacker to execute arbitrary code with the privileges of the current user. The vulnerability occurs when parsing a maliciously formatted sequence of ActionScript code inside of an Adobe Flash file. The problem exists in a certain ActionScript method. When the method is called with particular parameters, the ActionScript engine gets confused and takes a user supplied value as an object pointer which leads to an exploitable condition. iDefense has confirmed the existence of this vulnerability in the Flash Plugin version 10.1.82.76 and 10.1.85.3. A full list of vulnerable Adobe products can be found in Adobe Security Bulletin APSB11-02.
