Doc Text:
A flaw was found in FFmpeg. This vulnerability allows an attacker to cause a Denial of Service (DoS) by supplying a crafted video file with an invalid frame rate. When processing the malformed input during encoding configuration, an unvalidated denominator triggers a division-by-zero error that crashes the application.

Description OSIDB Bzimport 2026-11-10 13:18:27 UTC
FFmpeg through 9.0.2 contains a division by zero vulnerability in dovi_configure_ext() in libavcodec/dovi_rpuenc.c that allows attackers to crash the process via an unvalidated frame rate denominator. Attackers can supply a crafted HEVC or AV1 input with a nonzero frame rate numerator and zero denominator to the dovi_rpu bitstream filter or libx265, libaom, or libsvtav1 encoders, causing denial of service.
