========================================================================== Ubuntu Security Notice USN-2868-1 January 13, 2016
isc-dhcp vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.10 - Ubuntu 15.04 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS
Summary:
DHCP server, client, or relay could be made to crash if they received specially crafted network traffic.
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.
