Discussion

Microsoft Windows Graphics Rendering Engine WMF Format Code Execution Vulnerability

Microsoft Windows WMF graphics rendering engine is affected by a remote code execution vulnerability.

The problem presents itself when a user views a malicious WMF formatted file, triggering the vulnerability when the engine attempts to parse the file. A malicious file can cause an integer overflow that may facilitate heap memory corruption and arbitrary code execution.

Any code execution that occurs will be with SYSTEM privileges due to the nature of the affected engine. Successful exploitation can facilitate a remote compromise or local privilege escalation.
