Summary

FFmpeg through 9.0.2 contains a stack exhaustion vulnerability in av_encryption_init_info_free() in libavutil/encryption_info.c, which recursively frees AVEncryptionInitInfo linked lists built by the MOV demuxer's mov_read_pssh(). Attackers can supply a crafted MP4 file with tens of thousands of small pssh boxes to exhaust the stack and crash the process, while also causing quadratic CPU consumption.

Risk Assessment

An attacker can cause denial of service through process crash and CPU overload using a crafted media file.

Recommendation

Update FFmpeg to a patched version or apply the vendor patch.
