  <description>
    <p>
    A vulnerability leading to unauthorized file access has been
    found. A pre-existing symlink from /tmp/sudoers and /tmp/super.tab to a
    textfile will cause Smb4k to write the contents of these files to the
    target of the symlink, as Smb4k does not check for the existence of
    these files before writing to them.
    </p>
  </description>
  <impact type="high">
    <p>
    An attacker could acquire local privilege escalation by adding
    username(s) to the list of sudoers.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All smb4k users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-misc/smb4k-0.6.4&quot;</code>
  </resolution>
