Details
USN-531-1 fixed vulnerabilities in dhcp. The fixes were incomplete,
and only reduced the scope of the vulnerability, without fully solving
it. This update fixes the problem.
Original advisory details:
Nahuel Riva and Gerardo Richarte discovered that the DHCP server did not
correctly handle certain client options. A remote attacker could send
malicious DHCP replies to the server and execute arbitrary code.
