high Nessus Plugin ID 55857

Synopsis

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

Description

David Zych discovered that DHCP incorrectly handled certain malformed packets. A remote attacker could use this issue to cause DHCP to crash, 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.

Solution

Update the affected dhcp3-server and / or isc-dhcp-server packages.
