Using a specially-crafted repository, Git prior to versions 2.39.2, 2.38.4, 2.37.6, 2.36.5, 2.35.7, 2.34.7, 2.33.7, 2.32.6, 2.31.7, and 2.30.8 can be tricked into using its local clone optimization even when using a non-local transport. Though Git will abort local clones whose source `$GIT_DIR/objects` directory contains symbolic links, the `objects` directory itself may still be a symbolic link. These two may be combined to include arbitrary files based on known paths on the victim's filesystem within the malicious repository's working copy, allowing for data exfiltration in a similar manner as CVE-2022-39253.\n\nA fix has been prepared and will appear in v2.39.2 v2.38.4 v2.37.6 v2.36.5 v2.35.7 v2.34.7 v2.33.7 v2.32.6, v2.31.7 and v2.30.8. If upgrading is impractical, two short-term workarounds are available. Avoid cloning repositories from untrusted sources with `--recurse-submodules`. Instead, consider cloning repositories without recursively cloning their submodules, and instead run `git submodule update` at each layer. Before doing so, inspect each new `.gitmodules` file to ensure that it does not contain suspicious module URLs."}],"source":{"advisory":"GHSA-gw92-x3fm-3g3q","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T10:13:48.515Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/git/git/security/advisories/GHSA-gw92-x3fm-3g3q","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/git/git/security/advisories/GHSA-gw92-x3fm-3g3q"},{"name":"https://github.com/git/git/security/advisories/GHSA-3wp6-j8xr-qw85","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/git/git/security/advisories/GHSA-3wp6-j8xr-qw85"},{"name":"https://github.com/git/git/commit/c867e4fa180bec4750e9b54eb10f459030dbebfd","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/git/git/commit/c867e4fa180bec4750e9b54eb10f459030dbebfd"},{"url":"https://security.gentoo.org/glsa/202312-15","tags":["x_transferred"]}]}]}}
