FreeBSD : git -- multiple vulnerabilities (2a4472ed-5c0d-11f0-b991-291fce777db8)

high Nessus Plugin ID 241644

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 2a4472ed-5c0d-11f0-b991-291fce777db8 advisory.

 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. 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.


Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
