{"id":"DEBIAN-CVE-2026-33762","details":"go-git is an extensible git implementation library written in pure Go. Prior to version 5.17.1, go-git’s index decoder for format version 4 fails to validate the path name prefix length before applying it to the previously decoded path name. A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing. This issue only affects Git index format version 4. Earlier formats (go-git supports only v2 and v3) are not vulnerable to this issue. This issue has been patched in version 5.17.1.","modified":"2026-08-27T23:05:58.116389889Z","published":"2026-03-31T15:16:15.597Z","upstream":["CVE-2026-33762"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-33762"}],"affected":[{"package":{"name":"golang-github-go-git-go-git","ecosystem":"Debian:12","purl":"pkg:deb/debian/golang-github-go-git-go-git?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.11.0-1","5.11.0-2","5.11.0-3","5.11.0-4","5.12.0-1","5.13.2-1","5.14.0-1","5.16.2-1","5.17.0-1","5.17.1-1","5.19.1-1","5.4.2-3","5.4.2-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-33762.json"}},{"package":{"name":"golang-github-go-git-go-git","ecosystem":"Debian:13","purl":"pkg:deb/debian/golang-github-go-git-go-git?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.14.0-1","5.16.2-1","5.17.0-1","5.17.1-1","5.19.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-33762.json"}},{"package":{"name":"golang-github-go-git-go-git","ecosystem":"Debian:14","purl":"pkg:deb/debian/golang-github-go-git-go-git?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.17.1-1"}]}],"versions":["5.14.0-1","5.16.2-1","5.17.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-33762.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L"}]}
