{"id":"DEBIAN-CVE-2023-49568","details":"A denial of service (DoS) vulnerability was discovered in go-git versions prior to v5.11. This vulnerability allows an attacker to perform denial of service attacks by providing specially crafted responses from a Git server which triggers resource exhaustion in go-git clients.  Applications using only the in-memory filesystem supported by go-git are not affected by this vulnerability. This is a go-git implementation issue and does not affect the upstream git cli.","modified":"2026-09-15T09:02:47.018186539Z","published":"2024-01-12T11:15:12.680Z","upstream":["CVE-2023-49568"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-49568"}],"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-2023-49568.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"},{"fixed":"5.11.0-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-49568.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":"5.11.0-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-49568.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:N/A:H"}]}
