{"id":"UBUNTU-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":"2026-03-13T17:11:34.618010Z","published":"2024-01-12T11:15:00Z","related":["USN-8088-1"],"upstream":["CVE-2023-49568"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-49568"},{"type":"REPORT","url":"https://github.com/go-git/go-git/security/advisories/GHSA-mw99-9chc-xw7r"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-49568"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8088-1"}],"affected":[{"package":{"name":"golang-github-go-git-go-git","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/golang-github-go-git-go-git@5.4.2-3ubuntu0.1~esm1?arch=source&distro=esm-apps/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.4.2-3ubuntu0.1~esm1"}]}],"versions":["5.4.2-3"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_version":"5.4.2-3ubuntu0.1~esm1","binary_name":"go-git"},{"binary_version":"5.4.2-3ubuntu0.1~esm1","binary_name":"golang-github-go-git-go-git-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-49568.json"}},{"package":{"name":"golang-github-go-git-go-git","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/golang-github-go-git-go-git@5.4.2-4ubuntu0.24.04.3+esm2?arch=source&distro=esm-apps/noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.4.2-4ubuntu0.24.04.3+esm2"}]}],"versions":["5.4.2-3build1","5.4.2-4","5.4.2-4ubuntu0.24.04.1","5.4.2-4ubuntu0.24.04.2","5.4.2-4ubuntu0.24.04.2+esm1","5.4.2-4ubuntu0.24.04.3","5.4.2-4ubuntu0.24.04.3+esm1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_version":"5.4.2-4ubuntu0.24.04.3+esm2","binary_name":"go-git"},{"binary_version":"5.4.2-4ubuntu0.24.04.3+esm2","binary_name":"golang-github-go-git-go-git-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-49568.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
