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. wget url will fetch the file for you dpkg -i file.deb will install the referenced file.
