NVD Description

Note: Versions mentioned in the description apply only to the upstream git-all package and not the git-all package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

Git is a revision control system. Prior to versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1, a specially crafted .gitmodules file with submodule URLs that are longer than 1024 characters can used to exploit a bug in config.c::git_config_copy_or_rename_section_in_file(). This bug can be used to inject arbitrary configuration into a user's $GIT_DIR/config when attempting to remove the configuration section associated with that submodule. When the attacker injects configuration values which specify executables to run (such as core.pager, core.editor, core.sshCommand, etc.) this can lead to a remote code execution. A fix A fix is available in versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1. As a workaround, avoid running git submodule deinit on untrusted repositories or without prior inspection of any submodule sections in $GIT_DIR/config.
