A vulnerability has been reported in Adobe Flash Player, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to an error when parsing ActionScript that adds a custom function to the prototype of a predefined class. This results in incorrect interpretation of an object (i.e. object type confusion) when calling the custom function, which causes an invalid pointer to be dereferenced.
Successful exploitation allows execution of arbitrary code.
The vulnerability is reported in the following versions:
* Adobe Flash Player 10.2.153.1 and earlier versions for Windows, Macintosh, Linux, and Solaris
* Adobe Flash Player 10.2.154.25 and earlier for Chrome
* Adobe Flash Player 10.2.156.12 and earlier for Android
NOTE: The vulnerability is currently being actively exploited via Office Word documents (.doc) containing malicious Flash content.
Solution: Update to Flash Player 10.2.159.1 and AIR 2.6.19140.
