  <background>
    <p>
    The Cyrus IMAP Server is an efficient, highly-scalable IMAP e-mail
    server.
    </p>

  <description>
    <p>
    Multiple vulnerabilities have been discovered in the argument
    parsers of the 'partial' and 'fetch' commands of the Cyrus IMAP Server
    (CAN-2004-1012, CAN-2004-1013). There are also buffer overflows in the
    'imap magic plus' code that are vulnerable to exploitation as well
    (CAN-2004-1011, CAN-2004-1015).
    </p>
  </description>
  <impact type="high">
    <p>
    An attacker can exploit these vulnerabilities to execute arbitrary
    code with the rights of the user running the Cyrus IMAP Server.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Cyrus-IMAP Server users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-mail/cyrus-imapd-2.2.10&quot;</code>
  </resolution>
