This signature detects attempts to exploit a known vulnerability against Microsoft Windows Help. A successful attack can lead to arbitrary code execution.
The Microsoft Windows Help File viewer is reported prone to a heap-overflow vulnerability because it fails to perform boundary checks before copying user-supplied data into insufficiently sized memory buffers. This vulnerability presents itself when the application handles a specially crafted Windows Help ('.hlp') file. A successful attack may facilitate arbitrary code execution in the context of a vulnerable user who opens a malicious file. Failed exploit attempts will likely result in denial-of-service conditions.
