{"id":"DEBIAN-CVE-2026-123533","details":"gix-commitgraph before 0.42.0, as used in gitoxide before 0.61.0, contains a denial of service vulnerability because its commit-graph parser does not validate parent graph positions against the declared commit count or check the EDGE chunk length for 4-byte alignment. Attackers can supply a repository containing a crafted .git/objects/info/commit-graph file to trigger panics that abort gix merge-base, gix blame, and applications embedding gix.","modified":"2026-11-08T14:00:06.590346393Z","published":"2026-11-08T02:16:43.547Z","upstream":["CVE-2026-123533"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-123533"}],"affected":[{"package":{"name":"rust-gix-commitgraph","ecosystem":"Debian:13","purl":"pkg:deb/debian/rust-gix-commitgraph?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.25.1-1","0.29.0-1","0.37.0-1","0.38.0-1","0.39.0-1","0.41.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-123533.json"}},{"package":{"name":"rust-gix-commitgraph","ecosystem":"Debian:14","purl":"pkg:deb/debian/rust-gix-commitgraph?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.25.1-1","0.29.0-1","0.37.0-1","0.38.0-1","0.39.0-1","0.41.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-123533.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
