system.

When performing a local clone (where the source and target of the clone are on the same volume), Git copies the contents of the source's `$GIT_DIR/objects` directory into the destination by either creating hardlinks to the source contents, or copying them (if hardlinks are disabled via `--no-hardlinks`). A malicious actor could convince a victim to clone a repository with a symbolic link pointing at sensitive information on the victim's machine. This can be done either by having the victim clone a malicious repository on the same machine, or having them clone a malicious repository embedded as a bare repository via a submodule from any source, provided they clone with the `--recurse-submodules` option. Git does not create symbolic links in the `$GIT_DIR/objects` directory. The problem has been patched in the versions published on 2022-10-18, and backported to v2.30.x. Potential workarounds: Avoid cloning untrusted repositories using the `--local` optimization when on a shared machine, either by passing the `--no-local` option to `git clone` or cloning from a URL that uses the `file://` scheme. Alternatively, avoid cloning repositories from untrusted sources with `--recurse-submodules` or run `git config --global protocol.file.allow user`."}, {"lang": "es", "value": "Git es un sistema de control de revisiones distribuido, escalable y de c\u00f3digo abierto. Las versiones anteriores a la 2.30.6, 2.31.5, 2.32.4, 2.33.5, 2.34.5, 2.35.5, 2.36.3 y 2.37.4 est\u00e1n sujetas a una exposici\u00f3n de informaci\u00f3n confidencial a un actor malicioso. Cuando es llevado a cabo un clon local (en el que el origen y el destino del clon est\u00e1n en el mismo volumen), Git copia el contenido del directorio \"$GIT_DIR/objects\" del origen en el destino creando enlaces duros al contenido del origen o copi\u00e1ndolo (si los enlaces duros est\u00e1n deshabilitados por medio de \"--no-hardlinks\"). Un actor malicioso podr\u00eda convencer a una v\u00edctima de clonar un repositorio con un enlace simb\u00f3lico que apunte a informaci\u00f3n confidencial en la m\u00e1quina de la v\u00edctima. Esto puede hacerse ya sea que la v\u00edctima clone un repositorio malicioso en la misma m\u00e1quina, o haciendo que clone un repositorio malicioso insertado como repositorio desnudo por medio de un subm\u00f3dulo de cualquier fuente, siempre que clone con la opci\u00f3n \"--recurse-submodules\". Git no crea enlaces simb\u00f3licos en el directorio \"$GIT_DIR/objects\". El problema ha sido parcheado en las versiones publicadas el 18-10-2022, y retrocedido a v2.30.x.
