Description

In FFmpeg 4.0.1, due to a missing check for negative values of the mquant variable, the vc1_put_blocks_clamped function in libavcodec/vc1_block.c may trigger an out-of-array access while converting a crafted AVI file to MPEG4, leading to an information disclosure or a denial of service.

Solution(s)

  • ffmpeg-upgrade-4_0_2
