                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           dhcpcd
Advisory ID:            MDKSA-2003:003
Date:                   January 9th, 2003

Affected versions:      7.2, 8.0, 8.1, 8.2, 9.0,
                        Multi Network Firewall 8.2, 
                        Single Network Firewall 7.2
________________________________________________________________________

Problem Description:

 A vulnerability was discovered by Simon Kelley in the dhcpcd DHCP
 client daemon.  dhcpcd has the ability to execute an external script
 named dhcpcd-<interface>.exe when an IP address is assigned to that
 network interface.  The script sources the file
 /var/lib/dhcpcd/dhcpcd-<interface>.info which contains shell variables
 and DHCP assignment information.  The way quotes are handled inside
 these assignments is flawed, and a malicious DHCP server can execute
 arbitrary shell commands on the vulnerable DHCP client system.  This
 can also be exploited by an attacker able to spoof DHCP responses.
 
 Mandrake Linux packages contain a sample /etc/dhcpc/dhcpcd.exe file
 and encourages all users to upgrade immediately.  Please note that
 when you do upgrade, you will have to restart the network for the
 changes to take proper effect by issuing "service network restart"
 as root.
