Debian alert: New verion of dhcp released (updated)

  • Mailing list (Posted by dave on Jul 28, 2000 6:17 AM EDT)
  • Story Type: Security; Groups: Debian
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.
