<description>

<p>
|
|
The Mandriva Linux Engineering Team has reported a stack-based buffer
|
|
overflow in the subnet-mask handling of dhclient.

<impact type="high">
|
|
<p>
|
|
A remote attacker might set up a rogue DHCP server in a victim's local
|
|
network, possibly leading to the execution of arbitrary code with root
|
|
privileges.
|
|
</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-3.1.1-r1"</code>
