Integer signedness error in the decode_residual_block function in cavsdec.c in libavcodec in FFmpeg before 0.7.3 and 0.8.x before 0.8.2, and libav through 0.7.1, allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted Chinese AVS video (aka CAVS) file.

Security readout for executives and security teams

This is an old FFmpeg/libav media parsing flaw. A specially crafted Chinese AVS video file could corrupt memory and crash an application, with possible arbitrary code execution. Business risk depends on whether any service still processes untrusted video using the affected decoder versions. Exposure is likely limited to systems using affected FFmpeg or libav versions to parse untrusted Chinese AVS video content. Internet-facing upload, transcoding, preview, or media analysis pipelines would be the main concern. Prioritize if legacy FFmpeg/libav is present in production media ingestion. For modern, patched stacks, this is mainly a hygiene and inventory issue rather than an emergency. Mitigation focus: Inventory FFmpeg and libav versions in media-processing hosts, containers, and bundled applications.; Upgrade FFmpeg/libav packages beyond the affected versions identified in the CVE description.; Restrict or sandbox processing of untrusted video files where immediate upgrade is not possible..
