Description OSIDB Bzimport 2026-11-10 20:24:21 UTC 
FFmpeg through 9.0.2 contains an integer overflow vulnerability in the OpenEXR decoder's decode_frame() in libavcodec/exr.c that miscalculates the tiled block count. Attackers can supply a crafted tiled OpenEXR image with large dimensions and small tiles to skip decoding and disclose uninitialized memory or stale frame data.
