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.
