Technical details

A heap-based buffer overflow in FrameMaker's document parsing code (CWE-122) allows remote code execution when a victim opens a specially crafted file. The vulnerability requires local access and user interaction to open a malicious document; no authentication or privileged context is needed. Successful exploitation results in arbitrary code execution in the current user's security context.
