Heap-based buffer overflow in libmpdemux/aviheader.c in MPlayer 1.0rc1 and earlier allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a .avi file with certain large "indx truck size" and nEntriesInuse values, and a certain wLongsPerEntry value.

Security readout for executives and security teams

This is an old MPlayer AVI parsing flaw. A malicious AVI file could crash the player and may allow code execution, but the provided sources do not confirm exploitation in the wild or a CVSS score. Exposure is most likely where legacy MPlayer versions process untrusted AVI files, including desktop playback, automated media conversion, mail attachments, or upload pipelines. Treat as a legacy exposure cleanup item unless MPlayer processes external AVI files in production. Prioritize internet-facing or automated media workflows first. Mitigation focus: Identify any MPlayer 1.0rc1 or earlier installations.; Avoid processing untrusted AVI files with vulnerable MPlayer builds.; Check MPlayer and distribution vendor guidance for fixed packages..
