{"id":"DEBIAN-CVE-2026-100229","details":"A flaw was found in GStreamer's H.266 codec parser library (libgstcodecparsers). An out-of-bounds write vulnerability exists in the DCI parsing function, where a reserved field value is incorrectly accepted, causing the parser to write beyond the bounds of an internal structure. An attacker could exploit this by providing a specially crafted H.266 bitstream to a third-party application that uses this library API, potentially causing a crash or memory corruption. No standard GStreamer pipeline element currently invokes the affected code path.","modified":"2026-10-18T00:00:06.706828096Z","published":"2026-10-14T11:16:56.620Z","upstream":["CVE-2026-100229"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-100229"}],"affected":[{"package":{"name":"gst-plugins-bad1.0","ecosystem":"Debian:12","purl":"pkg:deb/debian/gst-plugins-bad1.0?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22.0-4","1.22.0-4+deb12u1","1.22.0-4+deb12u2","1.22.0-4+deb12u3","1.22.0-4+deb12u4","1.22.0-4+deb12u5","1.22.0-4+deb12u6","1.22.0-4+deb12u7","1.22.0-4+deb12u8","1.22.1-1","1.22.10-1","1.22.3-1","1.22.3-2","1.22.4-1","1.22.7-1","1.22.8-1","1.22.9-1","1.22.9-2","1.23.1-1","1.23.2-1","1.23.90-1","1.24.0-1","1.24.1-1","1.24.1-2","1.24.1-3","1.24.1-4","1.24.10-1","1.24.10-2","1.24.10-2+hurd.1","1.24.10-3","1.24.11-1","1.24.11-2","1.24.11-3","1.24.12-1","1.24.12-2","1.24.12-3","1.24.2-1","1.24.2-2","1.24.2-3","1.24.2-4","1.24.3-1","1.24.4-1","1.24.4-2","1.24.5-1","1.24.6-1","1.24.7-1","1.24.8-1","1.24.8-2","1.24.9-1","1.25.1-1","1.25.1-2","1.25.1-3","1.25.50-1","1.25.90-1","1.25.90-2","1.25.90-3","1.26.0-1","1.26.1-1","1.26.10-1","1.26.10-2","1.26.2-1","1.26.2-2","1.26.2-3","1.26.3-1","1.26.4-1","1.26.5-1","1.26.5-2","1.26.6-1","1.26.6-2","1.26.6-3","1.26.6-4","1.26.6-5","1.26.7-1","1.26.7-2","1.26.8-1","1.26.9-1","1.27.1-1","1.27.2-1","1.27.50-1","1.27.90-1","1.27.90-2","1.27.90-3","1.28.0-1","1.28.1-1","1.28.1-2","1.28.1-3","1.28.2-1","1.28.2-2","1.28.3-1","1.28.4-1","1.28.5-1","1.28.5-2","1.28.6-1","1.28.7-1","1.28.7-2","1.28.8-1","1.29.1-1","1.29.2-1","1.29.2-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-100229.json"}},{"package":{"name":"gst-plugins-bad1.0","ecosystem":"Debian:13","purl":"pkg:deb/debian/gst-plugins-bad1.0?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.26.10-1","1.26.10-2","1.26.2-3","1.26.2-3+deb13u1","1.26.2-3+deb13u2","1.26.2-3+deb13u3","1.26.3-1","1.26.4-1","1.26.5-1","1.26.5-2","1.26.6-1","1.26.6-2","1.26.6-3","1.26.6-4","1.26.6-5","1.26.7-1","1.26.7-2","1.26.8-1","1.26.9-1","1.27.1-1","1.27.2-1","1.27.50-1","1.27.90-1","1.27.90-2","1.27.90-3","1.28.0-1","1.28.1-1","1.28.1-2","1.28.1-3","1.28.2-1","1.28.2-2","1.28.3-1","1.28.4-1","1.28.5-1","1.28.5-2","1.28.6-1","1.28.7-1","1.28.7-2","1.28.8-1","1.29.1-1","1.29.2-1","1.29.2-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-100229.json"}},{"package":{"name":"gst-plugins-bad1.0","ecosystem":"Debian:14","purl":"pkg:deb/debian/gst-plugins-bad1.0?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.26.10-1","1.26.10-2","1.26.2-3","1.26.3-1","1.26.4-1","1.26.5-1","1.26.5-2","1.26.6-1","1.26.6-2","1.26.6-3","1.26.6-4","1.26.6-5","1.26.7-1","1.26.7-2","1.26.8-1","1.26.9-1","1.27.1-1","1.27.2-1","1.27.50-1","1.27.90-1","1.27.90-2","1.27.90-3","1.28.0-1","1.28.1-1","1.28.1-2","1.28.1-3","1.28.2-1","1.28.2-2","1.28.3-1","1.28.4-1","1.28.5-1","1.28.5-2","1.28.6-1","1.28.7-1","1.28.7-2","1.28.8-1","1.29.1-1","1.29.2-1","1.29.2-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-100229.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L"}]}
