The seg_write_packet function in libavformat/segment.c in ffmpeg 2.1.4 and earlier does not free the correct memory location, which allows remote attackers to cause a denial of service ("invalid memory handler") and possibly execute arbitrary code via a crafted video that triggers a use after free.

Security readout for executives and security teams

CVE-2014-9676 is a memory handling flaw in FFmpeg 2.1.4 and earlier. A crafted video could crash software that processes it, and the CVE description says arbitrary code execution may be possible. The available sources do not show active exploitation or a CVSS score. Exposure is most likely in systems still running FFmpeg 2.1.4 or earlier, especially services that ingest, transcode, segment, or otherwise process untrusted video files. Treat this as a legacy exposure cleanup item with higher urgency for internet-facing or customer-upload media processing. Lack of KEV listing reduces immediate emergency signal, but possible code execution keeps it security-relevant. Mitigation focus: Inventory FFmpeg versions across servers, containers, appliances, and media pipelines.; Upgrade FFmpeg packages following vendor or distribution guidance.; For Gentoo systems, review and apply GLSA-201606-09 guidance..
