Описание
FFmpeg before commit 9d786e4 contains a stack buffer overflow in the MPEG-PS muxer (libavformat/mpegenc.c). When muxing input with more streams than the muxer's fixed-size stack buffer accommodates, the buffer is overflowed. A crafted input with an excessive number of streams triggers the overflow during MPEG-PS muxing.
A flaw was found in FFmpeg. A stack buffer overflow exists in the MPEG-PS muxer. A local attacker or a user processing a specially crafted file with an excessive number of streams could trigger this flaw, leading to a buffer overflow. This could potentially result in denial of service or arbitrary code execution.
Отчет
The ffmpeg package is not shipped in base Red Hat Enterprise Linux. It is available through EPEL, Red Hat Enterprise Linux AI, and as a bundled dependency in Red Hat OpenShift AI container images. The vulnerable code resides in the MPEG-PS muxer (libavformat/mpegenc.c), which is compiled and shipped in all FFmpeg builds across these products. This is a stack buffer overflow triggered by input with an excessive number of streams.
Меры по смягчению последствий
No mitigation is currently available for this flaw.
