 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-4323-1 [email protected] https://www.debian.org/lts/security/ Andrej Shadura October 06, 2025 https://wiki.debian.org/LTS
 - -------------------------------------------------------------------------

 Package : git Version : 1:2.30.2-1+deb11u5 CVE ID : CVE-2025-27613 CVE-2025-46835 CVE-2025-48384

 CVE-2025-27613

 With Gitk, the Git history browser, 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).

 CVE-2025-46835

 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.

 CVE-2025-48384

 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.

 For Debian 11 bullseye, these problems have been fixed in version 1:2.30.2-1+deb11u5.

 We recommend that you upgrade your git packages.
