Descriptions

Arbitrary command execution is possible in Git before 2.20.2, 2.21.x before 2.21.1, 2.22.x before 2.22.2, 2.23.x before 2.23.1, and 2.24.x before 2.24.1 because a "git submodule update" operation can run commands found in the .gitmodules file of a malicious repository.

Una ejecución de comandos arbitrarios es posible en Git versiones anteriores a 2.20.2, versiones 2.21.x anteriores a 2.21.1, versiones 2.22.x anteriores a 2.22.2, versiones 2.23.x anteriores a 2.23.1 y versiones 2.24.x anteriores a 2.24.1, porque una operación "git submodule update" puede ejecutar comandos encontrados en el archivo .gitmodules de un repositorio malicioso.

Joern Schneeweisz and Nicolas Joly discovered that Git contained various security flaws. An attacker could possibly use these issues to overwrite arbitrary paths, execute arbitrary code, and overwrite files in the .git directory.
