CVE REFERENCE: CVE-2007-0934, CVE-2007-0936
CVSS SCORES: Base 5.6/ Temporal 4.1
THREAT: A remote code execution vulnerability exists in the way Microsoft Visio handles a specially crafted version number in a Visio (.VSD, VSS, or .VST) file. A remote code execution vulnerability exists in Microsoft Visio as a result of the way it incorrectly handles the parsing of packed objects within the Visio file format.
IMPACT: A malicious attacker can trick the user into opening a specially crafted file and can take complete control of the system.
SOLUTION: Microsoft has released some patches and workarounds for this vulnerability. Check Microsoft security bulletin MS07-030 for details. Microsoft has rated this issue as Important.

Windows Schannel Security Package Could Allow Remote Code Execution
