Upgrade mercurial to version 4.4.1 or higher.
Overview
mercurial is a distributed SCM tool written in Python.
Affected versions of this package are vulnerable to Arbitrary Code Execution. 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.
