Heap-based buffer overflow in mplayerc.exe in Media Player Classic (MPC) 6.4.9.0 and earlier, as used standalone and in mympc (aka CD-Storm) 1.0.0.1, StormPlayer 1.0.4, and possibly other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a .avi file with an "indx truck size" of 0xffffffff, and certain wLongsPerEntry and nEntriesInuse values.

Security readout for executives and security teams

This is an old media-player file parsing flaw. A specially malformed AVI file can crash Media Player Classic 6.4.9.0 or earlier, and the CVE says arbitrary code execution may be possible. Business risk is mainly where legacy Windows media tools remain installed or bundled in older applications. Exposure is most likely on unmanaged or legacy Windows endpoints that still have affected MPC-derived players installed, or where AVI files open by default in vulnerable bundled players. Modern, supported media players are less likely to be affected unless they include the vulnerable code path. Treat this as a legacy exposure cleanup item with high impact if vulnerable software remains in use. It is not a broad emergency based on the provided evidence, but unsupported media software that can process attacker-supplied files should be removed or isolated. Mitigation focus: Inventory endpoints for Media Player Classic 6.4.9.0 or earlier.; Check for mympc/CD-Storm 1.0.0.1 and StormPlayer 1.0.4 installations.; Remove unsupported vulnerable players where they are not required..
