{"id":"UBUNTU-CVE-2026-119729","details":"A flaw was found in GStreamer. An integer overflow vulnerability in the AV1 LEB128 variable-length integer parser allows a remote attacker to cause a crash in applications that process AV1 media content. By crafting a malformed AV1 bitstream containing an invalid LEB128-encoded value, an attacker can cause integer overflow in the parser, resulting in incorrect length values being used during stream processing, which can lead to a denial of service.","modified":"2026-11-04T03:30:31.568279764Z","published":"2026-11-03T00:00:00Z","upstream":["CVE-2026-119729"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-119729"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-119729"},{"type":"REPORT","url":"https://gstreamer.freedesktop.org/security/sa-2026-0014.html"},{"type":"REPORT","url":"https://gitlab.freedesktop.org/gstreamer/gstreamer/-/work_items/4994"},{"type":"REPORT","url":"https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/11245"},{"type":"REPORT","url":"https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/11259"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2026-119729"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2564126"}],"affected":[{"package":{"name":"gst-plugins-bad1.0","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/gst-plugins-bad1.0?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.0-3ubuntu5","1.2.1-1ubuntu1","1.2.1-1ubuntu2","1.2.2-1ubuntu1","1.2.2-1ubuntu2","1.2.2-1ubuntu4","1.2.3-1ubuntu1","1.2.3-1ubuntu2","1.2.4-1~ubuntu1","1.2.4-1~ubuntu1.1","1.2.4-1~ubuntu1.1+esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.2.4-1~ubuntu1.1+esm1","binary_name":"gstreamer1.0-hybris"},{"binary_name":"gstreamer1.0-plugins-bad","binary_version":"1.2.4-1~ubuntu1.1+esm1"},{"binary_name":"gstreamer1.0-plugins-bad-faad","binary_version":"1.2.4-1~ubuntu1.1+esm1"},{"binary_version":"1.2.4-1~ubuntu1.1+esm1","binary_name":"gstreamer1.0-plugins-bad-videoparsers"},{"binary_name":"libgstreamer-plugins-bad1.0-0","binary_version":"1.2.4-1~ubuntu1.1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119729.json"}},{"package":{"name":"gst-plugins-base1.0","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/gst-plugins-base1.0?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","1.8.3-1ubuntu0.1","1.8.3-1ubuntu0.2","1.8.3-1ubuntu0.3","1.8.3-1ubuntu0.3+esm1","1.8.3-1ubuntu0.3+esm2","1.8.3-1ubuntu0.3+esm3","1.8.3-1ubuntu0.3+esm4","1.8.3-1ubuntu0.3+esm5"],"ecosystem_specific":{"binaries":[{"binary_version":"1.8.3-1ubuntu0.3+esm5","binary_name":"gir1.2-gst-plugins-base-1.0"},{"binary_version":"1.8.3-1ubuntu0.3+esm5","binary_name":"gstreamer1.0-alsa"},{"binary_version":"1.8.3-1ubuntu0.3+esm5","binary_name":"gstreamer1.0-plugins-base"},{"binary_name":"gstreamer1.0-plugins-base-apps","binary_version":"1.8.3-1ubuntu0.3+esm5"},{"binary_version":"1.8.3-1ubuntu0.3+esm5","binary_name":"gstreamer1.0-x"},{"binary_version":"1.8.3-1ubuntu0.3+esm5","binary_name":"libgstreamer-plugins-base1.0-0"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119729.json"}},{"package":{"name":"gst-plugins-bad1.0","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/gst-plugins-bad1.0?arch=source&distro=esm-apps-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","1.7.1-1ubuntu3","1.7.1-1ubuntu4","1.7.2-1ubuntu1","1.7.90-1ubuntu2","1.7.91-1ubuntu1","1.8.0-1ubuntu1","1.8.1-1ubuntu0.1","1.8.2-1ubuntu0.1","1.8.2-1ubuntu0.2","1.8.3-1ubuntu0.2","1.8.3-1ubuntu0.2+esm1","1.8.3-1ubuntu0.2+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-gst-plugins-bad-1.0","binary_version":"1.8.3-1ubuntu0.2+esm2"},{"binary_name":"gstreamer1.0-hybris","binary_version":"1.8.3-1ubuntu0.2+esm2"},{"binary_name":"gstreamer1.0-plugins-bad","binary_version":"1.8.3-1ubuntu0.2+esm2"},{"binary_name":"gstreamer1.0-plugins-bad-faad","binary_version":"1.8.3-1ubuntu0.2+esm2"},{"binary_version":"1.8.3-1ubuntu0.2+esm2","binary_name":"gstreamer1.0-plugins-bad-videoparsers"},{"binary_name":"libgstreamer-plugins-bad1.0-0","binary_version":"1.8.3-1ubuntu0.2+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119729.json"}},{"package":{"name":"gst-plugins-base1.0","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/gst-plugins-base1.0?arch=source&distro=esm-infra%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12.3-1","1.12.4-1","1.13.1-1ubuntu1","1.13.91-1ubuntu1","1.14.0-1ubuntu1","1.14.0-2ubuntu1","1.14.1-1ubuntu1~ubuntu18.04.1","1.14.1-1ubuntu1~ubuntu18.04.2","1.14.4-1ubuntu1.1~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
