In gst_avi_demux_riff_parse_vprp(), the number of available gst_riff_vprp_video_field_desc entries is calculated by dividing the remaining buffer size by the attacker-controlled vprp->fields value, rather than by sizeof(gst_riff_vprp_video_field_desc). This can cause the parser to treat more field descriptors as available than fit in the input buffer, resulting in out-of-bounds reads. Processing a crafted AVI via playbin/decodebin can crash the application (denial of service). Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072)."}],"affected":[{"vendor":"GStreamer","product":"gst-plugins-good","versions":[{"status":"affected","version":"0","lessThan":"1.28.6","versionType":"semver"}],"packageName":"gst-plugins-good","collectionURL":"https://gitlab.freedesktop.org/gstreamer/gst-plugins-good","defaultStatus":"unaffected"},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 10","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"gstreamer1-plugins-good","defaultStatus":"affected","versions":[{"version":"0:1.26.7-2.el10_2.5","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/o:redhat:enterprise_linux:10.2"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"gstreamer1-plugins-good","defaultStatus":"affected","versions":[{"version":"0:1.16.1-7.el8_10.3","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:enterprise_linux:8::appstream"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"gstreamer1-plugins-good","defaultStatus":"affected","versions":[{"version":"0:1.22.12-7.el9_8.4","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:enterprise_linux:9::appstream"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 7","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"gstreamer1-plugins-good","defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:7"]}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:55434","name":"RHSA-2026:55434","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:55436","name":"RHSA-2026:55436","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:56966","name":"RHSA-2026:56966","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/security/cve/CVE-2026-73434","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2514807","name":"RHBZ#2514807","tags":["issue-tracking","x_refsource_REDHAT"]},{"url":"https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/12231"},{"url":"https://gstreamer.freedesktop.org/security/sa-2026-0072.html"}],"datePublic":"2026-08-05T00:00:00.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-125","description":"Out-of-bounds Read","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-125: Out-of-bounds Read","timeline":[{"lang":"en","time":"2026-08-12T16:20:06.270Z","value":"Reported to Red Hat."},{"lang":"en","time":"2026-08-05T00:00:00.000Z","value":"Made public."}],"credits":[{"lang":"en","value":"Red Hat would like to thank Seonwook Kim for reporting this issue."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-08-19T20:54:30.232Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-13T12:27:58.090050Z","id":"CVE-2026-73434","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-13T12:28:14.948Z"}}]}}
