Debian DLA-1224-1 : mercurial security update

This script is Copyright (C) 2017 Tenable Network Security, Inc.

Synopsis :

The remote Debian host is missing a security update.

Description :

A vulnerability was found in the Mercurial version control system
which could lead to remote arbitrary code execution.


A specially malformed Mercurial repository could cause Git
subrepositories to run arbitrary code in the form of a
.git/hooks/post-update script checked into the parent repository.
Typical use of Mercurial prevents construction of such repositories,
but they can be created programmatically.

For Debian 7 'Wheezy', these problems have been fixed in version

We recommend that you upgrade your mercurial packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.
