CVE-2014-125007: FFmpeg hevcpred_template.c intra_pred memory corruption

Security readout for executives and security teams

CVE-2014-125007 is a memory corruption issue in FFmpeg 2.0 when handling HEVC prediction logic. A remote attacker could trigger it through media processed by a vulnerable FFmpeg instance, with the documented impact limited to availability. No provided source shows active exploitation. Exposure is most likely where FFmpeg 2.0 processes untrusted or externally supplied HEVC/H.265 media, including upload, transcoding, preview, or media ingestion workflows. Systems using newer patched FFmpeg builds are not shown as affected by the provided sources. Prioritize remediation for internet-facing or customer-facing media processing services. The documented impact is availability rather than data theft, but unauthenticated remote reachability makes old FFmpeg 2.0 deployments operationally risky. Mitigation focus: Identify any deployed FFmpeg 2.0 binaries or bundled dependencies.; Apply the upstream FFmpeg patch referenced by the CVE sources.; Use vendor-packaged FFmpeg updates when FFmpeg comes from an OS or appliance vendor..
