  <impact type="normal">
    <p>The vulnerabilities allow local users to cause a denial of service (mtab
      corruption) via a crafted string. Also, local users could mount a CIFS
      share on an arbitrary mountpoint, and gain privileges via a symlink
      attack on the mountpoint directory file.

  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>Gentoo has discontinued support for mount-cifs. We recommend that users
      unmerge mount-cifs:

    <code>
      # emerge --unmerge "net-fs/mount-cifs"
    </code>
