CyberRota Analysis
AI-GeneratedFFmpeg versions from 4.4 to just before 9.0 are vulnerable to an out-of-bounds heap write in the GoPro CineForm HD decoder, which can be exploited by remote attackers through specially crafted AVI files. This vulnerability can lead to heap memory corruption and potentially allow for arbitrary code execution by overwriting critical pointers. Organizations using affected FFmpeg versions, particularly those handling video processing or streaming, should prioritize patching to mitigate this high-severity risk.

Original NVD Description
FFmpeg versions from 4.4 up to, but not including, 9.0 contain an out-of-bounds heap write vulnerability in the native GoPro CineForm HD (CFHD) decoder that allows remote attackers to corrupt heap memory by supplying a crafted AVI file during stream probing. The cfhd_decode() function fails to enforce the non-Bayer logical output-width invariant in the transform-type-2 reconstruction path, causing horiz_filter_clip() to write oversized 16-bit sample rows far beyond the allocated output frame buffer, which can be escalated to arbitrary code execution via overwrite of a live cleanup callback pointer.
