Description


Debian Security Advisory security@debian.org http://www.debian.org/security/ Michael Stone July 28, 2000


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. A previous Debian security advisory addressed this issue with package versions 2.0b1pl6-0.3 and 2.0-3potato1, but ISC has released a newer patch since the original advisory. You should install the latest packages even if you upgraded when the last advisory was released.

The reported vulnerability is fixed in the package dhcp-client-beta 2.0b1pl6-0.4 for the current stable release (debian 2.1) and in dhcp-client 2.0-3potato2 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.

Debian GNU/Linux 2.2 alias potato


Please note that woody has not been released yet. However since potato is very close to being released security updates are already being made available on security.debian.org.

Updates have been prepared for alpha, ia32, and sparc. These and other architectures will be included in the main potato distribution shortly.
