|
|
Configuration Protocol as specified in RFC 2131.

<description>
|
|
<p>
|
|
Christoph Biedl discovered that dhcpd does not properly handle certain
|
|
DHCP requests when configured both using "dhcp-client-identifier" and
|
|
"hardware ethernet".
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
A remote attacker might send a specially crafted request to dhcpd,
|
|
possibly resulting in a Denial of Service (daemon crash).
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All ISC DHCP users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/dhcp-3.1.2_p1"</code>
|
|
</resolution>
