Description

FFmpeg 2.1 through 9.0.2 contains an uninitialized memory disclosure vulnerability in pcx_decode_frame() in libavcodec/pcx.c that leaves scanline buffer bytes uncleared when input ends early. Attackers can supply a crafted truncated RLE-compressed or uncompressed PCX image to leak heap memory contents through the decoded pixels.
