In the Nikon metadata tag parser, a pointer can be dereferenced without verifying that data remains in the buffer, causing out-of-bounds reads. 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":6.1,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","version":"3.1"}],"modifiedAt":1793946742307,"publishedAt":1793946742307,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-73471"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2514821"},{"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":"5843b71fa03af237a62d66966d90c8d0f382eea88ff77dea02cf29b9e0812976","sources":[{"modifiedAt":1793946742307,"name":"CNA: redhat","retrievedAt":1793948934649,"url":"https://www.cve.org/CVERecord?id=CVE-2026-73471"}],"ssvc":null,"status":"published","title":"Gstreamer1-plugins-good: gstreamer: out-of-bounds read in avidemux nikon metadata tag parsing","updatedAt":1793948934649}
