Vulnerability details

The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.

The weakness exists  in the DecodeImage function due to heap-based buffer overflow. A remote attacker can trick the victim into opening a specially crafted "run-length count" in an image in a WMF file, trigger memory corruption and cause the service to crash or execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.
