Use-after-free vulnerability in the matroska_read_seek function in libavformat/matroskadec.c in FFmpeg before 2.5.1, as used in Google Chrome before 40.0.2214.91, allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted Matroska file that triggers improper maintenance of tracks data.

Security readout for executives and security teams

This is an older media-parsing flaw in FFmpeg’s Matroska handling, also present in Chrome before 40.0.2214.91. A crafted Matroska video file could crash affected software, and the CVE leaves open the possibility of other unspecified impact. The provided sources do not show active exploitation. Exposure is most likely in legacy systems using FFmpeg before 2.5.1, old Linux distribution packages, or Chrome before 40.0.2214.91. Modern managed endpoints are unlikely to be exposed unless obsolete media stacks remain embedded in products or appliances. Treat as a legacy exposure cleanup item unless old media-processing systems are internet-facing or ingest untrusted files. The main documented impact is service disruption, but memory corruption in parsers deserves timely removal from supported environments. Mitigation focus: Upgrade FFmpeg to 2.5.1 or a vendor-supported fixed package.; Ensure Chrome is at least 40.0.2214.91 where relevant.; Apply applicable Ubuntu, Gentoo, Red Hat, or openSUSE security updates..
