This signature detects attempts to exploit a known vulnerability in Microsoft HTML Help. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the client.
Microsoft HTML Help is prone to a remote stack-based buffer-overflow vulnerability. The vulnerability occurs when the application handles a malformed Microsoft HTML Help file ('.chm'). An attacker may exploit the issue to execute arbitrary code in the context of the application. Failed exploit attempts likely result in denial-of-service conditions.
