sp5xdec.c in the Sunplus SP5X JPEG decoder in libavcodec in FFmpeg before 0.6.3 and libav through 0.6.2, as used in VideoLAN VLC media player 1.1.9 and earlier and other products, performs a write operation outside the bounds of an unspecified array, which allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a malformed AMV file.

Security readout for executives and security teams

A malicious AMV video file could crash or potentially compromise software using an old FFmpeg/libavcodec Sunplus SP5X JPEG decoder. Business risk is highest where users or services process untrusted media with outdated FFmpeg, libav, VLC, or products bundling those libraries. Exposure is likely on legacy desktops, media-processing servers, appliances, or bundled applications that still include the affected FFmpeg/libavcodec decoder and accept AMV files from untrusted sources. Prioritize remediation for internet-facing or user-facing media processing systems. For ordinary endpoints, treat as important legacy cleanup unless users routinely open untrusted video files. Mitigation focus: Upgrade FFmpeg to 0.6.3 or later where applicable.; Replace libav through 0.6.2 with a vendor-fixed release.; Update VLC 1.1.9 and earlier to a vendor-supported fixed version..
