This signature detects attempts to exploit a remote code execution vulnerability in Adobe Flash Player.
Adobe Flash Player is a multimedia application for Microsoft Windows, Mozilla, and Apple technologies.
Adobe Flash Player is prone to a remote code-execution vulnerability that occurs because of a type confusion error. Specifically, this issue occurs when interpreter code of the Action Script Virtual Machine (AVM) fails to reset a with-scope pointer when an exception is caught.
Attackers can exploit this issue to execute arbitrary code in the context of the user running the affected application. Failed exploit attempts will likely cause a denial-of-service condition.
