CVE-2023-29007: Arbitrary configuration injection via `git submodule deinit`

Git is a revision control system. Prior to versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1, a specially crafted .gitmodules file with submodule URLs that are longer than 1024 characters can used to exploit a bug in config.c::git_config_copy_or_rename_section_in_file(). This bug can be used to inject arbitrary configuration into a user’s $GIT_DIR/config when attempting to remove the configuration section associated with that submodule. When the attacker injects configuration values which specify executables to run (such as core.pager, core.editor, core.sshCommand, etc.) this can lead to a remote code execution. A fix A fix is available in versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1. As a workaround, avoid running git submodule deinit on untrusted repositories or without prior inspection of any submodule sections in $GIT_DIR/config.

CVE
#vulnerability#git#rce#perl#ssh

Impact

A bug in the function responsible for renaming or deleting existing configuration sections in-place, git_config_copy_or_rename_section_in_file(), can result in improperly treating configuration values as the beginning of new sections when they are over 1,024 characters long.

This bug can be used to inject arbitrary configuration into a user’s $GIT_DIR/config when attempting to rename or remove a malicious configuration section. This can result in arbitrary execution of code, by inserting values for core.pager, core.editor, core.sshCommand and so on.

This may be exploited with overly-long submodule URLs, which are stored in a user’s $GIT_DIR/config upon initialization. Those URLs may be misinterpreted as containing new configuration material when removing those sections, e.g., with git submodule deinit.

Patches

A fix has been prepared and will appear in v2.30.9, v2.31.8, v2.32.7, v2.33.8, v2.34.8, v2.35.8, v2.36.6, v2.37.7, v2.38.5, v2.39.3 and v2.40.1.

Workarounds

Avoid running git submodule deinit, or git config --rename-section or git config --remove-section on untrusted repositories or without prior inspection of your $GIT_DIR/config.

Acknowledgements

Credit for finding this vulnerability goes to André Baptista and Vítor Pinho of Ethiack. The fix was developed by Taylor Blau, Jeff King, Patrick Steinhardt, and Johannes Schindelin.

CVE-2023-25652: Git 2.30.9 · git/git@668f2d5

Git is a revision control system. Prior to versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1, by feeding specially crafted input to `git apply --reject`, a path outside the working tree can be overwritten with partially controlled contents (corresponding to the rejected hunk(s) from the given patch). A fix is available in versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1. As a workaround, avoid using `git apply` with `--reject` when applying patches from an untrusted source. Use `git apply --stat` to inspect a patch before applying; avoid applying one that create a conflict where a link corresponding to the `*.rej` file exists.

CVE-2023-25815: Release Git for Windows 2.40.1 · git-for-windows/git

In Git for Windows, the Windows port of Git, no localized messages are shipped with the installer. As a consequence, Git is expected not to localize messages at all, and skips the gettext initialization. However, due to a change in MINGW-packages, the `gettext()` function's implicit initialization no longer uses the runtime prefix but uses the hard-coded path `C:\mingw64\share\locale` to look for localized messages. And since any authenticated user has the permission to create folders in `C:\` (and since `C:\mingw64` does not typically exist), it is possible for low-privilege users to place fake messages in that location where `git.exe` will pick them up in version 2.40.1. This vulnerability is relatively hard to exploit and requires social engineering. For example, a legitimate message at the end of a clone could be maliciously modified to ask the user to direct their web browser to a malicious website, and the user might think that the message comes from Git and is legitimate. It do...
