<background>
<p>
nfs-utils contains the client and daemon implementations for the NFS
protocol.
</p>
</background>
<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.
</p>
</description>
<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>
</resolution>
