mercurial - security update

Jesse Hertz of Matasano Security discovered that Mercurial, a
distributed version control system, is prone to a command injection
vulnerability via a crafted repository name in a clone command.

For the oldstable distribution (wheezy), this problem has been fixed in
version 2.2.2-4+deb7u1. This update also includes a fix for
CVE-2014-9390 previously scheduled for the next wheezy point release.

For the stable distribution (jessie), this problem has been fixed in
version 3.1.2-2+deb8u1.

For the unstable distribution (sid), this problem has been fixed in
version 3.4-1.

We recommend that you upgrade your mercurial packages.
