    <p>
    Jan Schneider of the Horde team discovered a vulnerability in the
    help viewer of the Horde Application Framework that could allow remote
    code execution (CVE-2006-1491). Paul Craig reported that
    "services/go.php" fails to validate the passed URL parameter correctly
    (CVE-2006-1260).
    </p>
  </description>
  <impact type="high">
    <p>
    An attacker could exploit the vulnerability in the help viewer to
    execute arbitrary code with the privileges of the web server user. By
    embedding a NULL character in the URL parameter, an attacker could
    exploit the input validation issue in go.php to read arbitrary files.
    </p>
  </impact>
  <workaround>
    <p>
    There are no known workarounds at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Horde Application Framework users should upgrade to the latest
    version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=www-apps/horde-3.1.1&quot;</code>
  </resolution>
