Gst-plugins-good: gst-plugins-good: qtdemux out-of-bounds heap read from invalid uncompressed video layout

Published Nov 9, 2026 CVSS 3.1 · 5.5 Medium EPSS < 1% KEV · Not listed
Description
A flaw was found in GStreamer's gst-plugins-good MOV/MP4 demuxer. When processing an uncompressed video track, qtdemux fails to validate the declared row alignment and chroma geometry before using them to build a video buffer layout. A crafted file can cause an out-of-bounds heap read while the sample is copied, potentially crashing the application and causing denial of service.

Remediation

Vendor Workaround

Update gst-plugins-good to version 1.28.3 or later. Where updating is not yet possible, avoid processing untrusted MOV/MP4 files with qtdemux; deployments that do not need MOV/MP4 support can disable the isomp4 plugin.
