In the subindex parser, missing validation of the entry count can cause excessive memory allocation and denial of service. Because avidemux is auto-plugged by playbin, decodebin, and gst-discoverer, opening or previewing a crafted AVI is sufficient to trigger the issue. Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072).","epss":null,"exploits":[],"kev":null,"metrics":[{"score":5.5,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793946742598,"publishedAt":1793946742598,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-73473"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2514915"},{"source":"CNA: redhat","tags":[],"url":"https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/12231"},{"source":"CNA: redhat","tags":[],"url":"https://gstreamer.freedesktop.org/security/sa-2026-0072.html"}],"remediation":[],"revision":"4d9588039a38bf8719270387cf64d28a5b183e62559ae98f875e766180fa103c","sources":[{"modifiedAt":1793946742598,"name":"CNA: redhat","retrievedAt":1793948936858,"url":"https://www.cve.org/CVERecord?id=CVE-2026-73473"}],"ssvc":null,"status":"published","title":"Gstreamer1-plugins-good: gstreamer: missing subindex entry count validation in avidemux leading to denial of service","updatedAt":1793948936858}
