    to overwrite arbitrary files.

  <background>
    <p>
    FireHOL is an iptables rules generator.
    </p>

  <description>
    <p>
    FireHOL insecurely creates temporary files with predictable names.
    </p>
  </description>
  <impact type="normal">
    <p>
    A local attacker could create malicious symbolic links to arbitrary
    system files. When FireHOL is executed, this could lead to these files
    being overwritten with the rights of the user launching FireHOL,
    usually the root user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All FireHOL users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-firewall/firehol-1.224"</code>
  </resolution>
