  <description>
    <p>
    TAKAHASHI Tamotsu has discovered that Mutt contains a boundary error in
    the "browse_get_namespace()" function in browse.c, which can be
    triggered when receiving an overly long namespace from an IMAP server.
    </p>
  </description>
  <impact type="normal">
    <p>
    A malicious IMAP server can send an overly long namespace to Mutt in
    order to crash the application, and possibly execute arbitrary code
    with the permissions of the user running Mutt.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Mutt users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=mail-client/mutt-1.5.11-r2&quot;</code>
  </resolution>
