Vulnerability Title
FFmpeg 4.4 < 9.0 Heap Out-of-Bounds Write in CFHD Decoder via AVI Demuxing
Vulnerability 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.

Vulnerability Title
FFmpeg 缓冲区错误漏洞
Vulnerability Description
FFmpeg是FFmpeg组织开源的一个多媒体处理框架。 FFmpeg 4.4版本至9.0之前版本存在缓冲区错误漏洞,该漏洞源于原生GoPro CineForm HD解码器的cfhd_decode()函数未正确执行非Bayer逻辑输出宽度检查,导致越界堆写入,可能破坏堆内存,并可通过覆盖清理回调指针升级为任意代码执行。
