    to overwrite arbitrary files.

  <description>
    <p>
    Jan Braun has discovered that the "fbgs" script provided by fbida
    insecurely creates temporary files in the "/var/tmp" directory.
    </p>
  </description>
  <impact type="normal">
    <p>
    A local attacker could create links in the temporary file
    directory, pointing to a valid file somewhere on the filesystem. When
    an affected script is called, this could result in the file being
    overwritten with the rights of the user running the script.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All fbida users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-gfx/fbida-2.03-r3"</code>
