    daemons.

  <description>
    <p>
    Improper bounds checking of user supplied data while parsing IMAP
    mailbox names can lead to overflowing the stack buffer.
    </p>
  </description>
  <impact type="high">
    <p>
    Successful exploitation requires an authenticated IMAP user to
    request a malformed mailbox name. This can lead to execution of
    arbitrary code with the permissions of the IMAP server.
    </p>
  </impact>
  <workaround>
    <p>
    There are no known workarounds at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All uw-imap users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-mail/uw-imap-2004g&quot;</code>
