Details

USN-1108-1 fixed vulnerabilities in DHCP. Due to an error, the patch to fix
the vulnerability was not properly applied on Ubuntu 9.10 and higher. This
update fixes the problem.

Original advisory details:

Sebastian Krahmer discovered that the dhclient utility incorrectly filtered
crafted responses. An attacker could use this flaw with a malicious DHCP
server to execute arbitrary code, resulting in root privilege escalation.
