📋 Description
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.
