Software Description: - isc-dhcp: DHCP server and client Details: Sebastian Poehn discovered that the DHCP server, client, and relay incorrectly handled certain malformed UDP packets. A remote attacker could use this issue to cause the DHCP server, client, or relay to stop responding, resulting in a denial of service. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 15.10: isc-dhcp-client 4.3.1-5ubuntu3.1 isc-dhcp-relay 4.3.1-5ubuntu3.1 isc-dhcp-server 4.3.1-5ubuntu3.1 isc-dhcp-server-ldap 4.3.1-5ubuntu3.1 Ubuntu 15.04: isc-dhcp-client 4.3.1-5ubuntu2.3 isc-dhcp-relay 4.3.1-5ubuntu2.3 isc-dhcp-server 4.3.1-5ubuntu2.3 isc-dhcp-server-ldap 4.3.1-5ubuntu2.3 Ubuntu 14.04 LTS: isc-dhcp-client 4.2.4-7ubuntu12.4 isc-dhcp-relay 4.2.4-7ubuntu12.4 isc-dhcp-server 4.2.4-7ubuntu12.4 isc-dhcp-server-ldap 4.2.4-7ubuntu12.4 Ubuntu 12.04 LTS: isc-dhcp-client 4.1.ESV-R4-0ubuntu5.10 isc-dhcp-relay 4.1.ESV-R4-0ubuntu5.10 isc-dhcp-server 4.1.ESV-R4-0ubuntu5.10 isc-dhcp-server-ldap 4.1.ESV-R4-0ubuntu5.10 In general, a standard system update will make all the necessary changes.
