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`."}],"source":{"advisory":"GHSA-475x-2q3q-hvwq","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T12:56:38.383Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/git/git/security/advisories/GHSA-475x-2q3q-hvwq","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/git/git/security/advisories/GHSA-475x-2q3q-hvwq"},{"name":"https://github.com/git/git/commit/508386c6c5857b4faa2c3e491f422c98cc69ae76","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/git/git/commit/508386c6c5857b4faa2c3e491f422c98cc69ae76"},{"name":"https://git-scm.com/book/en/v2/Customizing-Git-Git-Attributes#_export_subst","tags":["x_refsource_MISC","x_transferred"],"url":"https://git-scm.com/book/en/v2/Customizing-Git-Git-Attributes#_export_subst"},{"name":"https://git-scm.com/docs/pretty-formats#Documentation/pretty-formats.txt-emltltNgttruncltruncmtruncem","tags":["x_refsource_MISC","x_transferred"],"url":"https://git-scm.com/docs/pretty-formats#Documentation/pretty-formats.txt-emltltNgttruncltruncmtruncem"},{"url":"https://security.gentoo.org/glsa/202312-15","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-03-10T20:59:12.527761Z","id":"CVE-2022-41903","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-03-10T21:21:50.039Z"}}]}}
