FFmpeg through 9.0.2 contains a heap buffer overflow vulnerability in vdpau_hevc_start_frame() in libavcodec/vdpau_hevc.c that copies unbounded PPS tile counts into fixed-size VDPAU arrays. Attackers can supply crafted HEVC bitstreams with excessive tile columns or rows to write controlled 16-bit values past heap-allocated hwaccel data, corrupting memory in applications using VDPAU decoding.
FFmpeg <= 9.0.2Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
