<description>
<p>
Multiple vulnerabilities have been reported in gitweb that is part of
the git package:
</p>
<ul>
<li>
Shell metacharacters related to git_search are not properly sanitized
(CVE-2008-5516).
</li>
<li>
Shell metacharacters related to git_snapshot and git_object are not
properly sanitized (CVE-2008-5517).
</li>
<li>
The diff.external configuration variable as set in a repository can be
executed by gitweb (CVE-2008-5916).
</li>
</ul>
</description>
<impact type="high">
<p>
A remote unauthenticated attacker can execute arbitrary commands via
shell metacharacters in a query, remote attackers with write access to
a git repository configuration can execute arbitrary commands with the
privileges of the user running gitweb by modifying the diff.external
configuration variable in the repository and sending a crafted query to
gitweb.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All git users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-util/git-1.6.0.6"</code>
</resolution>
