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`."},{"lang":"es","value":"Git es un sistema de control de revisiones distribuido. `git log` puede mostrar confirmaciones en un formato arbitrario usando sus especificadores `--format`. Esta funcionalidad también está expuesta a \"git archive\" a través del atributo git \"export-subst\". Al procesar los operadores de relleno, hay un desbordamiento de enteros en `pretty.c::format_and_pad_commit()` donde `size_t` se almacena incorrectamente como `int` y luego se agrega como un desplazamiento a `memcpy()`. Este desbordamiento puede ser desencadenado directamente por un usuario que ejecuta un comando que invoca la maquinaria de formato de commit (por ejemplo, `git log --format=...`). También se puede activar indirectamente a través del archivo git mediante el mecanismo export-subst, que expande los especificadores de formato dentro de los archivos dentro del repositorio durante un archivo git. Este desbordamiento de enteros puede dar lugar a escrituras arbitrarias en el almacenamiento dinámico, lo que puede dar lugar a la ejecución de código arbitrario. El problema ha sido solucionado en las versiones publicadas el 17-01-2023, remontándose a la v2.30.7. Se recomienda a los usuarios que actualicen. Los usuarios que no puedan actualizar deben desactivar \"git archive\" en repositorios que no sean de confianza. Si expone el archivo git a través de `git daemon`, desactívelo ejecutando `git config --global daemon.uploadArch false`."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":5.9},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":5.9}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-190"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*","versionEndIncluding":"2.30.6","matchCriteriaId":"8D0B133C-FC2B-4CBF-8840-C85F6D650510"},{"vulnerable":true,"criteria":"cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*","versionStartIncluding":"2.31.0","versionEndIncluding":"2.31.5","matchCriteriaId":"BA5113C4-D095-4E76-A6C6-F849E11DFA9D"},{"vulnerable":true,"criteria":"cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*","versionStartIncluding":"2.32.0","versionEndIncluding":"2.32.4","matchCriteriaId":"B82E8E87-1083-45B9-A273-E6AB31548D56"},{"vulnerable":true,"criteria":"cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*","versionStartIncluding":"2.33.0","versionEndIncluding":"2.33.5","matchCriteriaId":"C9162726-CACE-4CB9-ACDE-204655D6BB3B"},{"vulnerable":true,"criteria":"cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*","versionStartIncluding":"2.34.0","versionEndIncluding":"2.34.5","matchCriteriaId":"65D149AF-5604-4109-A60B-CB7B5BBBEE87"},{"vulnerable":true,"criteria":"cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*","versionStartIncluding":"2.35.0","versionEndIncluding":"2.35.5","matchCriteriaId":"383C057B-98D3-4AC6-9D43-AE13CC81FEC4"},{"vulnerable":true,"criteria":"cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*","versionStartIncluding":"2.36.0","versionEndIncluding":"2.36.3","matchCriteriaId":"7B191BB2-D3C9-440D-8F7F-237BE0CBDB96"},{"vulnerable":true,"criteria":"cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*","versionStartIncluding":"2.37.0","versionEndIncluding":"2.37.4","matchCriteriaId":"E3F7AE8C-A383-442C-8E74-7BC13E8B251D"},{"vulnerable":true,"criteria":"cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*","versionStartIncluding":"2.38.0","versionEndIncluding":"2.38.2","matchCriteriaId":"28F8851A-1566-4F16-AEC4-2C09AC866C2A"},{"vulnerable":true,"criteria":"cpe:2.3:a:git-scm:git:2.39.0:*:*:*:*:*:*:*","matchCriteriaId":"CC98AC76-7F3E-45A0-9DE6-3D097CEE5199"}]}]}],"references":[{"url":"https://git-scm.com/book/en/v2/Customizing-Git-Git-Attributes#_export_subst","source":"security-advisories@github.com","tags":["Vendor Advisory"]},{"url":"https://git-scm.com/docs/pretty-formats#Documentation/pretty-formats.txt-emltltNgttruncltruncmtruncem","source":"security-advisories@github.com","tags":["Vendor Advisory"]},{"url":"https://github.com/git/git/commit/508386c6c5857b4faa2c3e491f422c98cc69ae76","source":"security-advisories@github.com","tags":["Patch","Release Notes","Third Party Advisory"]},{"url":"https://github.com/git/git/security/advisories/GHSA-475x-2q3q-hvwq","source":"security-advisories@github.com","tags":["Third Party Advisory"]},{"url":"https://security.gentoo.org/glsa/202312-15","source":"security-advisories@github.com"},{"url":"https://git-scm.com/book/en/v2/Customizing-Git-Git-Attributes#_export_subst","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]},{"url":"https://git-scm.com/docs/pretty-formats#Documentation/pretty-formats.txt-emltltNgttruncltruncmtruncem","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]},{"url":"https://github.com/git/git/commit/508386c6c5857b4faa2c3e491f422c98cc69ae76","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch","Release Notes","Third Party Advisory"]},{"url":"https://github.com/git/git/security/advisories/GHSA-475x-2q3q-hvwq","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]},{"url":"https://security.gentoo.org/glsa/202312-15","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
