AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Network-delivered malicious file requires user/pipeline to decode it (UI:R, PR:N); reliable RCE from an OOB write depends on heap state and mitigations, justifying AC:H over AC:L, with full CIA impact on the decoding process.

An out-of-bounds write vulnerability in FFmpeg's libavcodec library, specifically in the MagicYUV decoder, allows denial-of-service and, in some cases, can be exploited for remote code execution.
This vulnerability is associated with the file libavcodec/magicyuv.C.
This issue affects FFmpeg before version 8.1.2.

AnalysisAI
Out-of-bounds write in FFmpeg's libavcodec MagicYUV decoder (libavcodec/magicyuv.c) affects all FFmpeg versions before 8.1.2, allowing remote attackers to cause denial-of-service and potentially achieve remote code execution when a victim processes a crafted MagicYUV-encoded media file. No public exploit identified at time of analysis, but the broad deployment of FFmpeg across media players, transcoding pipelines, browsers, and server-side processing makes this a high-priority patch. EPSS and CISA KEV data were not provided in the input.
Technical ContextAI
FFmpeg is the de facto open-source multimedia framework used for decoding, encoding, transcoding, and streaming audio/video across countless desktop applications, mobile apps, cloud media pipelines, and embedded devices. libavcodec is FFmpeg's codec library, and the affected component is the MagicYUV decoder - MagicYUV is a fast lossless intermediate codec commonly used in video editing workflows. The root cause is CWE-787 (Out-of-bounds Write), meaning the decoder writes data past the bounds of an allocated buffer while parsing attacker-controlled MagicYUV bitstream fields, which can corrupt adjacent heap memory and, with appropriate heap grooming, lead to control-flow hijack. The affected CPE cpe:2.3:a:ffmpeg:ffmpeg:*:*:*:*:*:*:*:* covers all upstream FFmpeg builds prior to 8.1.2; downstream redistributors (Linux distros, Homebrew, application bundles statically linking libavcodec) inherit the flaw until they rebase.
RemediationAI
Upstream fix available (PR https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23159); released patched version 8.1.2 is referenced in the description but should be verified against the official FFmpeg release once tags are published. Upgrade FFmpeg and any redistributed libavcodec to 8.1.2 or later, and rebuild downstream applications that statically link libavcodec. If immediate patching is not possible, compensating controls include disabling the MagicYUV decoder at build time (configure with --disable-decoder=magicyuv), filtering MagicYUV input at ingest by rejecting FourCC 'MAGY' / 'M8RG' / 'M8RA' / 'M8G0' / 'M8Y0' etc. before handoff to libavcodec, or sandboxing transcoder workers (seccomp, gVisor, separate user namespace) so an exploited decoder cannot pivot - note the trade-off that disabling the decoder will break legitimate MagicYUV workflows (typically video editors), and ingest filtering by FourCC can be bypassed by containers that re-tag streams.
