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`."}, {"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. 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\""}], "lastModified": "2023-12-27T10:15:37.640", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "28199E8F-36D0-46F8-AF0A-9460390BE56F", "versionEndExcluding": "2.30.6"}, {"criteria": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E095AAE7-18C2-4957-9740-FC804860B9C2", "versionEndExcluding": "2.31.5", "versionStartIncluding": "2.31.0"}, {"criteria": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "459EE43E-40FB-45BE-A1CC-51435E9F92AD", "versionEndExcluding": "2.32.4", "versionStartIncluding": "2.32.0"}, {"criteria": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "2CBDDA42-F5EC-4747-BF3C-16683D684702", "versionEndExcluding": "2.33.5", "versionStartIncluding": "2.33.0"}, {"criteria": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D7691E22-145E-4D97-A6E0-6515742781B9", "versionEndExcluding": "2.34.5", "versionStartIncluding": "2.34.0"}, {"criteria": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E02396C2-BB34-4D18-917E-DA56EA7B58B9", "versionEndExcluding": "2.35.5", "versionStartIncluding": "2.35.0"}, {"criteria": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "51BEAEEC-9D9D-4CFE-8958-43BFE87DE501", "versionEndExcluding": "2.36.3", "versionStartIncluding": "2.36.0"}, {"criteria": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "566CF89C-AC39-47D7-B3DE-633B2237F816", "versionEndExcluding": "2.37.4", "versionStartIncluding": "2.37.0"}, {"criteria": "cpe:2.3:a:git-scm:git:2.38.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "1AFEECCB-B8DB-4270-A860-C2BA1C7B267C"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:fedoraproject:fedora:35:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "80E516C0-98A4-4ADE-B69F-66A772E2BAAA"}, {"criteria": "cpe:2.3:o:fedoraproject:fedora:36:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "5C675112-476C-4D7C-BCB9-A2FB2D0BC9FD"}, {"criteria": "cpe:2.3:o:fedoraproject:fedora:37:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E30D0E6F-4AE8-4284-8716-991DFA48CC5D"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:apple:xcode:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "CECD39AA-41F4-4638-B59A-C5E928B585C3", "versionEndExcluding": "14.1"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "07B237A9-69A3-4A9C-9DA0-4E06BD37AE73"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
