{"cve":"CVE-2022-41903","nvd":{"published":"2023-01-17T23:15:15.690","modified":"2026-06-17T05:04:01.900","status":"Modified","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`.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-190"],"references":["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://github.com/git/git/commit/508386c6c5857b4faa2c3e491f422c98cc69ae76","https://github.com/git/git/security/advisories/GHSA-475x-2q3q-hvwq","https://security.gentoo.org/glsa/202312-15"],"products":["git-scm:git"],"source":"nvd","synced_at":"2026-10-19T21:37:34.931465858+00:00"},"epss":{"cve":"CVE-2022-41903","score":0.44268,"percentile":0.98759,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
