<description>
|
|
<p>
|
|
Michele Marcionelli reported that nfs-utils invokes the hosts_ctl()
|
|
function with the wrong order of arguments, which causes TCP Wrappers
|
|
to ignore netgroups.

<impact type="normal">
|
|
<p>
|
|
A remote attacker could bypass intended access restrictions, i.e. NFS
|
|
netgroups, and gain access to restricted services.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

</p>
|

</workaround>
|
|
<resolution>
|
|
<p>
|
|
All nfs-utils users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-fs/nfs-utils-1.1.3"</code>
