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

In Mercurial before 4.4.1, it is possible that a specially malformed repository can cause Git subrepositories to run arbitrary code in the form of a .git/hooks/post-update script checked into the repository. Typical use of Mercurial prevents construction of such repositories, but they can be created programmatically.
