+Git v2.43.7 Release Notes
+=========================
+
+This release includes fixes for CVE-2025-27613, CVE-2025-27614,
+CVE-2025-46334, CVE-2025-46835, CVE-2025-48384, CVE-2025-48385, and
+CVE-2025-48386.
+
+Fixes since v2.43.6
+-------------------
+
+ * CVE-2025-27613, Gitk:
+
+ When a user clones an untrusted repository and runs Gitk without
+ additional command arguments, any writable file can be created and
+ truncated. The option "Support per-file encoding" must have been
+ enabled. The operation "Show origin of this line" is affected as
+ well, regardless of the option being enabled or not.
+
+ * CVE-2025-27614, Gitk:
+
+ A Git repository can be crafted in such a way that a user who has
+ cloned the repository can be tricked into running any script
+ supplied by the attacker by invoking `gitk filename`, where
+ `filename` has a particular structure.
+
+ * CVE-2025-46334, Git GUI (Windows only):
+
+ A malicious repository can ship versions of sh.exe or typical
+ textconv filter programs such as astextplain. On Windows, path
+ lookup can find such executables in the worktree. These programs
+ are invoked when the user selects "Git Bash" or "Browse Files" from
+ the menu.
+
+ * CVE-2025-46835, Git GUI:
+
+ When a user clones an untrusted repository and is tricked into
+ editing a file located in a maliciously named directory in the
+ repository, then Git GUI can create and overwrite any writable
+ file.
+
+ * CVE-2025-48384, Git:
+
+ 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.
+
+ * CVE-2025-48385, Git:
+
+ 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.
+
+ * CVE-2025-48386, Git:
+
+ The wincred credential helper uses a static buffer (`target`) as a
+ unique key for storing and comparing against internal storage. This
+ credential helper does not properly bounds check the available
+ space remaining in the buffer before appending to it with
+ `wcsncat()`, leading to potential buffer overflows.
