    <p>
    Vixie Cron is a command scheduler with extended syntax over cron.
    </p>
  </background>
  <description>
    <p>
    Roman Veretelnikov discovered that Vixie Cron fails to properly
    check whether it can drop privileges accordingly if setuid() in
    do_command.c fails due to a user exceeding assigned resource limits.
    </p>
  </description>
  <impact type="high">
    <p>
    Local users can execute code with root privileges by deliberately
    exceeding their assigned resource limits and then starting a command
    through Vixie Cron. This requires resource limits to be in place on the
    machine.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Vixie Cron users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=sys-process/vixie-cron-4.1-r9"</code>
