+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.
