Description
FFmpeg through 9.0.2 contains a heap buffer overflow vulnerability in pcm_bluray_decode_frame() in libavcodec/pcm-bluray.c on big-endian hosts. Attackers can supply a crafted Blu-ray (M2TS) LPCM stream whose payload length is not a multiple of the sample size, writing attacker-controlled bytes past the audio frame buffer.
