DLA-1005-1 mercurial -- LTS security update

Date Reported:
29 Jun 2017
Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 861243.
In Mitre's CVE dictionary: CVE-2017-9462.
More information:

In Mercurial before 4.1.3, "hg serve --stdio" allows remote authenticated users to launch the Python debugger, and consequently execute arbitrary code, by using --debugger as a repository name.

For Debian 7 Wheezy, these problems have been fixed in version 2.2.2-4+deb7u4.

We recommend that you upgrade your mercurial packages.
