    Summary: Mercurial vulnerable to arbitrary code injection

    Details: 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.
