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 before 3.1.60 contains a regular expression denial of service vulnerability in Actor.name_email_regex that processes commit author and committer fields. Attackers can craft a commit object with a malformed author field containing an unterminated angle bracket to cause quadratic backtracking, exhausting CPU resources for over two minutes per commit access.
