Description
FFmpeg through 9.0.2 contains a memory leak vulnerability in libxevd_receive_frame() in libavcodec/libxevd.c that fails to free pkt_au when an access unit produces no picture. Attackers can supply a crafted EVC stream with many access units containing only parameter sets or non-frame NAL units to exhaust memory in the decoding application.
