NVD Description

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

GitPython is a python library used to interact with Git repositories. Prior to version 3.1.49, GitConfigParser.set_value() passes values to Python's configparser without validating for newlines. GitPython's own _write() converts embedded newlines into indented continuation lines (e.g. \n becomes \n\t), but Git still accepts an indented [core] stanza as a section header — so the injected core.hooksPath becomes effective configuration. Any Git operation that invokes hooks (commit, merge, checkout) will then execute scripts from the attacker-controlled path. This issue has been patched in version 3.1.49.
