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.
