Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-48384 affects Git, a distributed revision control system. The vulnerability arises from how Git handles carriage return (CR) and line feed (LF) characters when reading and writing configuration values. Git strips trailing CRLF characters when reading a config value. However, when writing a config entry, values with a trailing CR are not quoted, leading to the CR being lost when the config is later read. This can lead to issues when initializing submodules. If a submodule path contains a trailing CR, the altered path (without the CR) is read, causing the submodule to be checked out to an incorrect location. If a symbolic link exists that points the altered path to the submodule's hooks directory, and the submodule contains an executable post-checkout hook, the script may be unintentionally executed after checkout, potentially leading to arbitrary code execution. This vulnerability is fixed in Git versions 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.

Description: 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.
