<p>
dhcpcd is a standards compliant DHCP client daemon. It requests an
IP address and other information from the DHCP server, automatically
configures the network interface, and tries to renew the lease time.
</p>
</background>
<description>
<p>
infamous42md discovered that dhcpcd can be tricked to read past
the end of the supplied DHCP buffer. As a result, this might lead to a
crash of the daemon.
</p>
</description>
<impact type="normal">
<p>
With a malicious DHCP server an attacker could cause a Denial of
Service by crashing the DHCP client.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All dhcpcd users should upgrade to the latest available version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-misc/dhcpcd-1.3.22_p4-r11&quot;</code>
</resolution>
