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>

<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.

<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 ">=net-misc/dhcpcd-1.3.22_p4-r11"</code>
