    <p>
    maildrop is the mail filter/mail delivery agent that is used by the
    Courier Mail Server.

  <description>
    <p>
    Christoph Anton Mitterer reported that maildrop does not properly drop
    its privileges when run as root.
    </p>
  </description>
  <impact type="high">
    <p>
    A local attacker could create a specially crafted .mailfilter file,
    possibly leading to the execution of arbitrary commands with the "root"
    group privileges. NOTE: Successful exploitation requires that maildrop
    is run as root with the -d option.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All maildrop users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=mail-filter/maildrop-2.4.2"</code>
