  </background>
  <description>
    <p>
    Possible single byte overflows have been found in the imapd annotate
    extension and mailbox handling code. Furthermore stack buffer overflows
    have been found in fetchnews, the backend and imapd.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker, who could be an authenticated user or an admin of a
    peering news server, could 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-2.2.12&quot;</code>
  </resolution>
