<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.
</p>
</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:
</p>
<code>
# emerge --unmerge "net-fs/mount-cifs"
</code>
</resolution>
