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. 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. 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.

According to the versions of the git packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    Gitk is a Tcl/Tk based Git history browser. Starting with 1.7.0, when a user clones an untrusted     repository and runs gitk without additional command arguments, files for which the user has write     permission can be created and truncated. The option Support per-file encoding must have been enabled     before in Gitk's Preferences. This option is disabled by default. The same happens when Show origin of     this line is used in the main window (regardless of whether Support per-file encoding is enabled or not).
    This vulnerability is fixed in 2.43.7, 2.44.4, 2.45.4, 2.46.4, 2.47.3, 2.48.2, 2.49.1, and     2.50.1.(CVE-2025-27613)

    Git GUI allows you to use the Git source control management tools via a GUI. A malicious repository can     ship versions of sh.exe or typical textconv filter programs such as astextplain. Due to the unfortunate     design of Tcl on Windows, the search path when looking for an executable always includes the current     directory. The mentioned programs are invoked when the user selects Git Bash or Browse Files from the     menu. This vulnerability is fixed in 2.43.7, 2.44.4, 2.45.4, 2.46.4, 2.47.3, 2.48.2, 2.49.1, and     2.50.1.(CVE-2025-46334)

    Git GUI allows you to use the Git source control management tools via a 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 files for which the user has write permission. This     vulnerability is fixed in 2.43.7, 2.44.4, 2.45.4, 2.46.4, 2.47.3, 2.48.2, 2.49.1, and     2.50.1.(CVE-2025-46835)

    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 development team reports:
    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-2025-46835: 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.

    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.
