Doc Text:
A flaw was found in FFmpeg. This vulnerability allows an attacker to cause a Denial of Service (DoS) by supplying a specially crafted Vorbis audio stream containing malformed metadata. When processing the media stream, the parser repeatedly attempts to parse the invalid data for every packet, consuming excessive CPU resources and causing the application to hang or become unresponsive.

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.
