Description
FFmpeg through 9.0.2 contains an uninitialized memory disclosure vulnerability in the GEM raster image decoder in libavcodec/gemdec.c that exposes uninitialized row-buffer bytes. Attackers can supply a crafted GEM .img image using SKIP or pattern opcodes to copy uninitialized heap memory into decoded frames, disclosing heap contents.
