<background>
<p>CVS (Concurrent Versions System) is an open-source network-transparent
version control system. It contains both a client utility and a server.
</p>
</background>
<description>
<p>It was discovered that when CVS is configured to use SSH for remote
repositories it allows remote attackers to execute arbitrary code through
a repository URL with a specially crafted hostname.
</p>
</description>
<impact type="normal">
<p>A remote attacker, by enticing a user to clone a specially crafted
repository, could possibly execute arbitrary code with the privileges of
the process.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All CVS users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-vcs/cvs-1.12.12-r12"
</code>
</resolution>
