QID 354808

git is a revision control system.
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 victims filesystem within the malicious repositorys working copy, allowing for data exfiltration in a similar manner as( CVE-2022-39253.
A 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. (
( CVE-2023-22490) git, a revision control system, is vulnerable to path traversal 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.
By feeding a crafted input to `git apply`, a path outside the working tree can be overwritten as the user who is running `git apply`.
A 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.
