Description OSIDB Bzimport 2026-11-10 19:49:32 UTC 
FFmpeg through 9.0.2 contains a denial of service vulnerability in libavcodec/vorbis_parser.c that re-parses invalid extradata for every packet when valid_extradata remains false. Attackers can supply crafted Ogg or Matroska Vorbis streams with large invalid extradata and many packets to exhaust CPU during demuxing or probing.
