Debian DLA-2003-1 : isc-dhcp security update

medium Nessus Plugin ID 131248

Language:

Synopsis

The remote Debian host is missing a security update.

Description

An issue has been found in isc-dhcp, a server for automatic IP address assignment.

The number of simultaneous open TCP connections to OMAPI port of the server has to be limited to 200 in order to avoid a denial of service.

For Debian 8 'Jessie', this problem has been fixed in version 4.3.1-6+deb8u4.

We recommend that you upgrade your isc-dhcp packages.

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

Solution

Upgrade the affected packages.
