    <p>
    Dmitry E. Oboukhov reported that the rccs and STUFF scripts do not

    be further occurances of insecure temporary file usage.

  <impact type="normal">
    <p>
    A local attacker could perform symlink attacks to overwrite arbitrary
    files with the privileges of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    LMBench has been removed from Portage. We recommend that users unmerge
    LMBench:
    </p>
    <code>
    # emerge --unmerge app-benchmarks/lmbench</code>
