    <p>
    Eric Romang discovered that gtkdiskfree insecurely creates a
    predictable temporary file to handle command output.
    </p>
  </description>
  <impact type="normal">
    <p>
    A local attacker could create a symbolic link in the temporary
    files directory, pointing to a valid file somewhere on the filesystem.
    When gtkdiskfree is executed, this would result in the file being
    overwritten with the rights of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All gtkdiskfree users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-admin/gtkdiskfree-1.9.3-r1&quot;</code>
  </resolution>
