HTTP: Microsoft Help Workshop HPJ OPTIONS Section Buffer Overflow

This signature detects attempts to exploit a known vulnerability against Microsoft Help Workshop. An attacker can create malicious Web pages containing dangerous HPJ files with a long HLP reference, which if visited, can gain control of a victim's system.

Extended Description

Microsoft Help Workshop fails to properly bounds-check user-supplied input in '.hpj' help project files. An attacker may use a malformed '.hpj' file containing an unusually long string to cause a stack-based buffer overflow, allowing the execution of arbitrary code. A successful exploit would result in the execution of arbitrary code within the security context of the user running the affected application.
