{"id":"CVE-2022-41903","summary":"Integer overflow in `git archive`, `git log --format` leading to RCE in git","details":"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`.","aliases":["GHSA-475x-2q3q-hvwq"],"modified":"2026-04-19T03:46:42.191883Z","published":"2023-01-17T22:17:16.123Z","related":["ALSA-2023:0610","ALSA-2023:0611","CGA-2vq3-chq9-2r3w","SUSE-SU-2023:0108-1","SUSE-SU-2023:0109-1","SUSE-SU-2023:0110-1","openSUSE-SU-2024:12625-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/41xxx/CVE-2022-41903.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-190"]},"references":[{"type":"WEB","url":"https://git-scm.com/book/en/v2/Customizing-Git-Git-Attributes#_export_subst"},{"type":"WEB","url":"https://git-scm.com/docs/pretty-formats#Documentation/pretty-formats.txt-emltltNgttruncltruncmtruncem"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/41xxx/CVE-2022-41903.json"},{"type":"ADVISORY","url":"https://github.com/git/git/security/advisories/GHSA-475x-2q3q-hvwq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-41903"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202312-15"},{"type":"FIX","url":"https://github.com/git/git/commit/508386c6c5857b4faa2c3e491f422c98cc69ae76"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/git/git","events":[{"introduced":"3dcec76d9df911ed8321007b1d197c1a206dc164"},{"fixed":"37ed7bf0f13d204ccb6b8e7e2fbcf7b3bf13e25c"}]}],"versions":["v2.38.0","v2.38.1","v2.38.2"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-41903.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:H/I:H/A:H"}]}
