Vulnerability from gsd

Details
Git is an open source, scalable, distributed revision control system. Versions prior to 2.30.6, 2.31.5, 2.32.4, 2.33.5, 2.34.5, 2.35.5, 2.36.3, and 2.37.4 are subject to exposure of sensitive information to a malicious actor. 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`.

Versions prior to 2.30.6, 2.31.5, 2.32.4, 2.33.5, 2.34.5, 2.35.5, 2.36.3, and 2.37.4 are subject to exposure of sensitive information to a malicious actor. 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\u0027s `$GIT_DIR/objects` directory into the destination by either creating hardlinks to the source contents, or copying them (if hardlinks are disabled via `--no-hardlinks`). A malicious actor could convince a victim to clone a repository with a symbolic link pointing at sensitive information on the victim\u0027s machine. This can be done either by having the victim clone a malicious repository on the same machine, or having them clone a malicious repository embedded as a bare repository via a submodule from any source, provided they clone with the `--recurse-submodules` option. Git does not create symbolic links in the `$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`."

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. Posibles mitigaciones: Evite clonar repositorios no confiables usando la optimizaci\u00f3n \"--local\" cuando est\u00e9 en una m\u00e1quina compartida, ya sea pasando la opci\u00f3n \"--no-local\" a \"git clone\" o clonando desde una URL que use el esquema \"file://\". Alternativamente, evita clonar repositorios de fuentes no confiables con \"--recurse-submodules\" o ejecuta \"git config --global protocol.file.allow user\""
