Description Guilherme de Almeida Suckevicz 2026-09-14 18:15:27 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

FFmpeg before 9.0 has an out-of-bounds read because there is insufficiently padded extradata in the MOV parsing path in mov_read_iacb in libavformat/mov.c.
