Description OSIDB Bzimport 2026-11-10 13:02:28 UTC 
FFmpeg through 9.0.2 contains a memory leak vulnerability in vc1_decode_frame() in libavcodec/vc1dec.c that leaks slice buffers when init_get_bits8() fails. Attackers can supply crafted files with repeated oversized VC-1 slices exceeding the bit reader limit to exhaust memory of decoding applications.
