  <impact type="normal">
    <p>
    A remote attacker could exploit these vulnerabilities by sending a
    specially crafted package, possibly causing a Denial of Service
    condition, or resulting in information disclosure.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Asterisk users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-misc/asterisk-1.2.37"</code>
    <p>
    NOTE: This is a legacy GLSA. Updates for all affected architectures are
    available since January 5, 2010. It is likely that your system is
    already no longer affected by this issue.
