| Description | FFmpeg 2.1 through 9.0.2 contains a use of uninitialized resource vulnerability in the PCX decoder that allows attackers to leak heap memory through truncated RLE scanlines. Attackers can craft a PCX image whose RLE data ends early, causing pcx_decode_frame() to copy uninitialized av_malloc() buffer contents into visible decoded pixels. | 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. |
