+    <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 &quot;&gt;=dev-util/git-1.6.0.6&quot;</code>
