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 tambi\u00e9n est\u00e1 expuesta a \"git archive\" a trav\u00e9s 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=...`). Tambi\u00e9n se puede activar indirectamente a trav\u00e9s 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 din\u00e1mico, lo que puede dar lugar a la ejecuci\u00f3n de c\u00f3digo arbitrario. El problema ha sido solucionado en las versiones publicadas el 17-01-2023, remont\u00e1ndose 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.
