Package: dhcp-client-beta (dhcp-client)
Vulnerability type: remote root exploit
Debian-specific: no

The versions of the ISC DHCP client in debian 2.1 (slink) and debian 2.2
(potato) are vulnerable to a root exploit. The OpenBSD team reports that the
client inappropriately executes commands embedded in replies sent from a dhcp
server. This means that a malicious dhcp server can execute commands on the
client with root privilages. 

The reported vulnerability is fixed in the package dhcp-client-beta
2.0b1pl6-0.3 for the current stable release (debian 2.1) and in dhcp-client
2.0-3potato1 for the frozen pre-release (debian 2.2). The dhcp server and relay
agents are built from the same source as the client; however, the server and
relay agents are not vulnerable to this issue and do not need to be upgraded.
We recommend upgrading your dhcp-client-beta and dhcp-client immediately.
