Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS

Summary:

An attacker could send crafted input to DHCP and cause it to crash.

Software Description: - isc-dhcp: DHCP server and client - dhcp3: DHCP server and client

Details:

David Zych discovered that DHCP incorrectly handled certain malformed packets. A remote attacker could use this issue to cause DHCP to crash, resulting in a denial of service.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 11.04:
isc-dhcp-server 4.1.1-P1-15ubuntu9.1

Ubuntu 10.10:
dhcp3-server 3.1.3-2ubuntu6.3

Ubuntu 10.04 LTS:
dhcp3-server 3.1.3-2ubuntu3.3

Ubuntu 8.04 LTS:
dhcp3-server 3.0.6.dfsg-1ubuntu9.3

In general, a standard system update will make all the necessary changes.
