Ubuntu 12.04 LTS / 14.04 LTS / 15.04 / 15.10 : isc-dhcp vulnerability (USN-2868-1)

Medium Nessus Plugin ID 87916


The remote Ubuntu host is missing one or more security-related patches.


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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected packages.
