{"id":"DEBIAN-CVE-2026-25934","details":"go-git is a highly extensible git implementation library written in pure Go. Prior to 5.16.5, a vulnerability was discovered in go-git whereby data integrity values for .pack and .idx files were not properly verified. This resulted in go-git potentially consuming corrupted files, which would likely result in unexpected errors such as object not found. For context, clients fetch packfiles from upstream Git servers. Those files contain a checksum of their contents, so that clients can perform integrity checks before consuming it. The pack indexes (.idx) are generated locally by go-git, or the git cli, when new .pack files are received and processed. The integrity checks for both files were not being verified correctly. This vulnerability is fixed in 5.16.5.","modified":"2026-08-27T23:05:48.216168255Z","published":"2026-02-09T23:16:05.937Z","upstream":["CVE-2026-25934"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-25934"}],"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-2026-25934.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-2026-25934.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":"5.17.0-1"}]}],"versions":["5.14.0-1","5.16.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-25934.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N"}]}
