A badly formed packet with an invalid IPv4 UDP length field can cause an ISC DHCP server, client, or relay program to terminate abnormally (CVE-2015-8605). The dhcp package has been updated to version 4.3.3-P1, which fixes this issue and several other bugs. Also, the package has also been enhanced to provide better support for running a DHCPv6 server (mga#17177).
