"Mercurial version 4.5 and earlier contains a Incorrect Access Control
(CWE-285) vulnerability in Protocol server that can result in
Unauthorized data access. This attack appear to be exploitable via
network connectivity. This vulnerability appears to have been fixed in
4.5.1.

This update also fixes a regression inroduced in 2.2.2-4+deb7u5 which
makes the testsuite fail non-deterministically.

For Debian 7 'Wheezy', these problems have been fixed in version
2.2.2-4+deb7u7.

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."
