ssvc Trackcvss 6.9
FFmpeg through 9.0.2 contains an out-of-bounds read vulnerability in libxevd_receive_frame() in libavcodec/libxevd.c that fails to validate NAL unit length prefixes against remaining packet data. Attackers can supply crafted EVC media with oversized 4-byte NAL length prefixes, causing libxevd to read past the packet buffer, crashing the application or exposing adjacent heap memory.
