{"id":"UBUNTU-CVE-2026-125041","details":"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.","modified":"2026-11-11T09:39:20.950773733Z","published":"2026-11-10T00:00:00Z","upstream":["CVE-2026-125041"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-125041"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-125041"},{"type":"REPORT","url":"access.redhat.com/downloads/content/package-browser"},{"type":"REPORT","url":"gitlab.freedesktop.org/gstreamer/gstreamer/-/commit/8ab9fa446cc1e5672fef118acbe43d2a503f3913"},{"type":"REPORT","url":"gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/11584"},{"type":"REPORT","url":"gstreamer.freedesktop.org/security/sa-2026-0025.html"},{"type":"REPORT","url":"security-tracker.debian.org/tracker/cve-2026-125041"}],"affected":[{"package":{"name":"gst-plugins-good1.0","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/gst-plugins-good1.0?arch=source&distro=esm-infra-legacy%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.0-1ubuntu1","1.6.1-1ubuntu1","1.6.2-1ubuntu1","1.7.1-1ubuntu1","1.7.2-1ubuntu1","1.7.90-1ubuntu1","1.7.91-1ubuntu1","1.8.0-1ubuntu1","1.8.1-1ubuntu0.1","1.8.2-1ubuntu0.1","1.8.2-1ubuntu0.2","1.8.2-1ubuntu0.3","1.8.3-1ubuntu0.3","1.8.3-1ubuntu0.4","1.8.3-1ubuntu0.5","1.8.3-1ubuntu0.5+esm1","1.8.3-1ubuntu0.5+esm2","1.8.3-1ubuntu0.5+esm3","1.8.3-1ubuntu0.5+esm4","1.8.3-1ubuntu0.5+esm5"],"ecosystem_specific":{"binaries":[{"binary_version":"1.8.3-1ubuntu0.5+esm5","binary_name":"gstreamer1.0-plugins-good"},{"binary_name":"gstreamer1.0-pulseaudio","binary_version":"1.8.3-1ubuntu0.5+esm5"},{"binary_version":"1.8.3-1ubuntu0.5+esm5","binary_name":"libgstreamer-plugins-good1.0-0"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-125041.json"}},{"package":{"name":"gst-plugins-good1.0","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/gst-plugins-good1.0?arch=source&distro=esm-infra%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12.3-1ubuntu1","1.12.4-1ubuntu1","1.13.1-1ubuntu1","1.13.91-1ubuntu1","1.14.0-1ubuntu1","1.14.1-1ubuntu1~ubuntu18.04.1","1.14.4-1ubuntu1~ubuntu18.04.1","1.14.5-0ubuntu1~18.04.1","1.14.5-0ubuntu1~18.04.2","1.14.5-0ubuntu1~18.04.3","1.14.5-0ubuntu1~18.04.3+esm1","1.14.5-0ubuntu1~18.04.3+esm2","1.14.5-0ubuntu1~18.04.3+esm3","1.14.5-0ubuntu1~18.04.3+esm4","1.14.5-0ubuntu1~18.04.3+esm5"],"ecosystem_specific":{"binaries":[{"binary_name":"gstreamer1.0-gtk3","binary_version":"1.14.5-0ubuntu1~18.04.3+esm5"},{"binary_version":"1.14.5-0ubuntu1~18.04.3+esm5","binary_name":"gstreamer1.0-plugins-good"},{"binary_version":"1.14.5-0ubuntu1~18.04.3+esm5","binary_name":"gstreamer1.0-pulseaudio"},{"binary_name":"gstreamer1.0-qt5","binary_version":"1.14.5-0ubuntu1~18.04.3+esm5"},{"binary_version":"1.14.5-0ubuntu1~18.04.3+esm5","binary_name":"libgstreamer-plugins-good1.0-0"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-125041.json"}},{"package":{"name":"gst-plugins-good1.0","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/gst-plugins-good1.0?arch=source&distro=esm-infra%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.16.1-1ubuntu1","1.16.2-1ubuntu1","1.16.2-1ubuntu2","1.16.2-1ubuntu2.1","1.16.3-0ubuntu1","1.16.3-0ubuntu1.1","1.16.3-0ubuntu1.2","1.16.3-0ubuntu1.3","1.16.3-0ubuntu1.3+esm1","1.16.3-0ubuntu1.3+esm2","1.16.3-0ubuntu1.3+esm3","1.16.3-0ubuntu1.3+esm4","1.16.3-0ubuntu1.3+esm5"],"ecosystem_specific":{"binaries":[{"binary_name":"gstreamer1.0-gtk3","binary_version":"1.16.3-0ubuntu1.3+esm5"},{"binary_version":"1.16.3-0ubuntu1.3+esm5","binary_name":"gstreamer1.0-plugins-good"},{"binary_name":"gstreamer1.0-pulseaudio","binary_version":"1.16.3-0ubuntu1.3+esm5"},{"binary_version":"1.16.3-0ubuntu1.3+esm5","binary_name":"gstreamer1.0-qt5"},{"binary_version":"1.16.3-0ubuntu1.3+esm5","binary_name":"libgstreamer-plugins-good1.0-0"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-125041.json"}},{"package":{"name":"gst-plugins-good1.0","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/gst-plugins-good1.0?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.18.5-1ubuntu2","1.18.5-1ubuntu3","1.20.0-2ubuntu1","1.20.1-1ubuntu1","1.20.3-0ubuntu1","1.20.3-0ubuntu1.1","1.20.3-0ubuntu1.3","1.20.3-0ubuntu1.4","1.20.3-0ubuntu1.5","1.20.3-0ubuntu1.6","1.20.3-0ubuntu1.7","1.20.3-0ubuntu1.8","1.20.3-0ubuntu1.9","1.20.3-0ubuntu1.10","1.20.3-0ubuntu1.11"],"ecosystem_specific":{"binaries":[{"binary_name":"gstreamer1.0-gtk3","binary_version":"1.20.3-0ubuntu1.11"},{"binary_name":"gstreamer1.0-plugins-good","binary_version":"1.20.3-0ubuntu1.11"},{"binary_name":"gstreamer1.0-pulseaudio","binary_version":"1.20.3-0ubuntu1.11"},{"binary_version":"1.20.3-0ubuntu1.11","binary_name":"gstreamer1.0-qt5"},{"bi
