msnmsgr.exe in Windows Live Messenger (WLM) 2009 build 14.0.8064.206, and other 14.0.8064.x builds, allows remote attackers to cause a denial of service (application crash) via a modified header in a packet, as possibly demonstrated by a UTF-8.0 value of the charset field in the Content-Type header line. NOTE: this has been reported as a format string vulnerability by some sources, but the provenance of that information is unknown.

Security readout for executives and security teams

This CVE describes a crash in Windows Live Messenger 2009. A remote party could send a malformed packet header that causes the Messenger application to stop working. The available sources describe denial of service only; they do not establish code execution, data theft, or current real-world exploitation. Exposure is likely limited to environments still running Windows Live Messenger 2009 14.0.8064.x builds. Modern estates should verify whether any legacy client installations remain before treating this as material risk. Low priority unless the organization still depends on Windows Live Messenger 2009. If present, remediation is mainly legacy software cleanup to prevent nuisance outages and reduce unsupported-client risk. Mitigation focus: Inventory endpoints for Windows Live Messenger 2009 14.0.8064.x installations.; Check Microsoft or vendor guidance for any historical update or replacement advice.; Remove or disable legacy Messenger clients where business use is not required..
