{"id":"CVE-2022-41903","state":"PUBLISHED","title":"Integer overflow in `git archive`, `git log --format` leading to RCE in git","description":"Git is distributed revision control system. `git log` can display commits in an arbitrary format using its `--format` specifiers. This functionality is also exposed to `git archive` via the `export-subst` gitattribute. When processing the padding operators, there is a integer overflow in `pretty.c::format_and_pad_commit()` where a `size_t` is stored improperly as an `int`, and then added as an offset to a `memcpy()`. This overflow can be triggered directly by a user running a command which invokes the commit formatting machinery (e.g., `git log --format=...`). It may also be triggered indirectly through git archive via the export-subst mechanism, which expands format specifiers inside of files within the repository during a git archive. This integer overflow can result in arbitrary heap writes, which may result in arbitrary code execution. The problem has been patched in the versions published on 2023-01-17, going back to v2.30.7. Users are advised to upgrade. Users who are unable to upgrade should disable `git archive` in untrusted repositories. If you expose git archive via `git daemon`, disable it by running `git config --global daemon.uploadArch false`.","publishedAt":"2023-01-17T22:17:16.123Z","updatedAt":"2025-03-10T21:21:50.039Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["git git"],"affected":[{"vendor":"git","product":"git","versions":[{"version":"< 2.30.7","status":"affected"},{"version":">= 2.31.0, < 2.31.6","status":"affected"},{"version":">= 2.32.0, < 2.32.5","status":"affected"},{"version":">= 2.33.0, < 2.33.6","status":"affected"},{"version":">= 2.34.0, < 2.34.6","status":"affected"},{"version":">= 2.35.0, < 2.35.6","status":"affected"},{"version":">= 2.36.0, < 2.36.4","status":"affected"},{"version":">= 2.37.0, < 2.37.5","status":"affected"},{"version":">= 2.38.0, < 2.38.3","status":"affected"},{"version":"= 2.39.0","status":"affected"}]}],"references":["https://github.com/git/git/security/advisories/GHSA-475x-2q3q-hvwq","https://github.com/git/git/commit/508386c6c5857b4faa2c3e491f422c98cc69ae76","https://git-scm.com/book/en/v2/Customizing-Git-Git-Attributes#_export_subst","https://git-scm.com/docs/pretty-formats#Documentation/pretty-formats.txt-emltltNgttruncltruncmtruncem","https://security.gentoo.org/glsa/202312-15"],"weaknesses":["CWE-190"],"ingestedAt":"2026-10-29T19:50:37.819Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/41xxx/CVE-2022-41903.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2022-41903","state":"PUBLISHED","datePublished":"2023-01-17T22:17:16.123Z","dateUpdated":"2025-03-10T21:21:50.039Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2022-09-30T16:38:28.931Z"},"containers":{"cna":{"title":"Integer overflow in `git archive`, `git log --format` leading to RCE in git","descriptions":[{"lang":"en","value":"Git is distributed revision control system. `git log` can display commits in an arbitrary format using its `--format` specifiers.
