CVE-2025-48386

Security Fix(es):

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. When reading a config value, Git strips any trailing carriage return and line feed (CRLF). When writing a config entry, values with a trailing CR are not quoted, causing the CR to be lost when the config is later read. When initializing a submodule, if the submodule path contains a trailing CR, the altered path is read resulting in the submodule being checked out to an incorrect location. If a symlink exists that points the altered path to the submodule hooks directory, and the submodule contains an executable post-checkout hook, the script may be unintentionally executed after checkout. This vulnerability is fixed in v2.43.7, v2.44.4, v2.45.4, v2.46.4, v2.47.3, v2.48.2, v2.49.1, and v2.50.1.(CVE-2025-48384)

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. The wincred credential helper uses a static buffer (target) as a unique key for storing and comparing against internal storage.

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. When cloning a repository Git knows to optionally fetch a bundle advertised by the remote server, which allows the server-side to offload parts of the clone to a CDN. The Git client does not perform sufficient validation of the advertised bundles, which allows the remote side to perform protocol injection. This protocol injection can cause the client to write the fetched bundle to a location controlled by the adversary. The fetched content is fully controlled by the server, which can in the worst case lead to arbitrary code execution. The use of bundle URIs is not enabled by default and can be controlled by the bundle.heuristic config option. Some cases of the vulnerability require that the adversary is in control of where a repository will be cloned to. This either requires social engineering or a recursive clone with submodules. These cases can thus be avoided by disabling…

These are all security issues fixed in the git-2.50.1-1.1 package on the GA media of openSUSE Tumbleweed.

This update for git fixes the following issues:

• Update to 2.51.0

  • UI, Workflows & Features
    • Userdiff patterns for the R language have been added.
    • Documentation for "git send-email" has been updated with a bit more credential helper and OAuth information.
    • "git cat-file --batch" learns to understand %(objectmode) atom to allow the caller to tell missing objects (due to repository corruption) and submodules (whose commit objects are OK to be missing) apart.
    • "git diff --no-index dirA dirB" can limit the comparison with pathspec at the end of the command line, just like normal "git diff".
    • "git subtree" (in contrib/) learned to grok GPG signing its commits.
    • "git whatchanged" that is longer to type than "git log --raw" which is its modern rough equivalent has outlived its usefulness more than 10 years ago. Plan to deprecate and remove it.
    • An interchange format for stash entries is defined, and subcommand of "git stash" to import/export has been added.
    • "git merge/pull" has been taught the "--compact-summary" option to use the compact-summary format, intead of diffstat, when showing the summary of the incoming changes.
    • "git imap-send" has been broken for a long time, which has been resurrected and then taught to talk OAuth2.0 etc.
    • Some error messages from "git imap-send" has been updated.
    • When "git daemon" sees a signal while attempting to accept() a new client, instead of retrying, it skipped it by mistake, which has been corrected.
    • The reftable ref backend has matured enough; Git 3.0 will make it the default format in a newly created repositories by default.
    • "netrc" credential helper has been improved to understand textual service names (like smtp) in addition to the numeric port numbers (like 25).
    • Lift the limitation to use changed-path filter in "git log" so that it can be used for a pathspec with multiple literal paths.
    • Clean up the way how signature on commit objects are exported to and imported from fast-import stream.
    • Remove unsupported, unused, and unsupportable old option from "git log".
    • Document recently added "git imap-send --list" with an example.
    • "git pull" learned to pay attention to pull.autostash configuration variable, which overrides rebase/merge.autostash.
    • "git for-each-ref" learns "--start-after" option to help applications that want to page its output.
    • "git switch" and "git restore" are declared to be no longer experimental.
    • "git -c alias.foo=bar foo -h baz" reported "'foo' is aliased to 'bar'" and then went on to run "git foo -h baz", which was unexpected. Tighten the rule so that alias expansion is reported only when "-h" is the sole option.
  • Performance, Internal Implementation, Development Support etc.
    • "git pack-objects" learned to find delta bases from blobs at the same path, using the --path-walk API.
    • CodingGuidelines update.
    • Add settings for Solaris 10 & 11.
    • Meson-based build/test framework now understands TAP output generated by our tests.
    • "Do not explicitly initialize to zero" rule has been clarified in the CodingGuidelines document.
    • A test helper "test_seq" function learned the "-f <fmt>" option, which allowed us to simplify a lot of test scripts.
    • A lot of stale stuff has been removed from the contrib/ hierarchy.
    • "git push" and "git fetch" are taught to update refs in batches to gain performance.
    • Some code paths in "git prune" used to ignore the passed-in repository object and used the the_repository singleton instance instead, which has been corrected.
    • Update ".clang-format" and ".editorconfig" to match our style guide a bit better.
    • "make coccicheck"…

This update for git fixes the following issues:

Update to 2.51.0:

• CVE-2025-27613: arbitrary writable file creation and truncation in Gitk (bsc#1245938)
• CVE-2025-27614: arbitrary script execution via repo clonation in gitk (bsc#1245939)
• CVE-2025-46835: untrusted repository cloning can lead to arbitrary writable file creation in Git GUI (bsc#1245942)
• CVE-2025-48384: script may be unintentionally executed after checkout due to CRLF transforming (bsc#1245943)
• CVE-2025-48385: arbitrary code execution due to protocol injection via fetching advertised bundle (bsc#1245946)
• CVE-2025-48386: buffer overflow in static buffer 'target' in wincred credential helper (bsc#1245947)

Avi Halachmi discovered that Git incorrectly managed file modification constraints with Gitk. An attacker could possibly use this issue to create or write to arbitrary files on the system. (CVE-2025-27613)

Avi Halachmi discovered that Git incorrectly handled arguments when invoking the Gitk utility. If a user were tricked into cloning a malicious Git repository, an attacker could possibly use this issue to run arbitrary commands. This issue only affected Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04. (CVE-2025-27614)

Johannes Sixt discovered that Git incorrectly managed file modification constraints with Git GUI. If a user were tricked into editing a file in a malicious Git repository, an attacker could possibly use this issue to create or write to arbitrary files on the system. (CVE-2025-46835)

David Leadbeater discovered that Git incorrectly stripped CRLF characters when editing configuration files. An attacker could possibly use this issue to execute arbitrary code. (CVE-2025-48384)

David Leadbeater discovered that Git incorrectly handled verification when fetching remote Git repositories. An attacker could possibly use this issue to perform protocol injection, leading to arbitrary code execution. This issue only affected Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04. (CVE-2025-48385)

David Leadbeater discovered that Git incorrectly handled memory with the wincred credential helper. An attacker could possibly use this issue to cause a denial of service. (CVE-2025-48386)
