Name of the Vulnerable Software and Affected Versions
FFmpeg versions 4.4 through 8.x
Description
An out-of-bounds heap write exists in the native GoPro CineForm HD (CFHD) decoder. A remote attacker can corrupt heap memory by providing a specially crafted AVI file during stream probing. The issue occurs because the
cfhd decode() function does not enforce the non-Bayer logical output-width invariant in the transform-type-2 reconstruction path. This leads the horiz filter clip() function to write oversized 16-bit sample rows beyond the allocated output frame buffer, which may allow arbitrary code execution by overwriting a live cleanup callback pointer.Recommendations
Update FFmpeg to version 9.0 or later.
