CVE-2026-12706 (GCVE-0-2026-12706)

Vulnerability from cvelistv5 – Published: 2026-06-19 10:55 – Updated: 2026-06-22 19:28

Title

Ffmpeg: ffmpeg: heap use-after-free read in rasc decoder decode_move()

Summary

A use-after-free vulnerability was found in FFmpeg's RASC video decoder. The decode_move() function initializes a read pointer into a decompressed buffer, but a subsequent reallocation of that same buffer during move-table processing leaves the pointer dangling. An attacker could exploit this by providing a specially crafted AVI file containing a malicious RASC video stream. When a user opens or plays the file, the decoder reads from freed heap memory, which could lead to a denial of service (crash).

Severity

OESA-2026-2826 (CVE-2026-12706)

Vulnerability from osv_openeuler – Published: 2026-07-06 11:11 – Updated: 2026-08-06 11:11 – Source website

Summary

ffmpeg security update

Details

FFmpeg is a complete and free Internet live audio and video broadcasting solution for Linux/Unix. It also includes a digital VCR. It can encode in real time in many formats including MPEG1 audio and video, MPEG4, h263, ac3, asf, avi, real, mjpeg, and flash.

Security Fix(es):

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.(CVE-2026-8461)

Severity

8.8 (High)
