openSUSE Security Update : dhcp (openSUSE-2016-887)

medium Nessus Plugin ID 92506

Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

This update for dhcp fixes the following issues :

Security issue fixed :

 - CVE-2016-2774: Fixed a denial of service attack against the DHCP server over the OMAPI TCP socket, which could be used by network adjacent attackers to make the DHCP server non-functional (bsc#969820).

Non security issues fixed :

 - Rename freeaddrinfo(), getaddrinfo() and getnameinfo() in the internal libirs library that does not consider /etc/hosts and /etc/nsswitch.conf to use irs_ prefix.
 This prevents name conflicts which would result in overriding standard glibc functions used by libldap.
 (bsc#972907)

This update was imported from the SUSE:SLE-12-SP1:Update update project.

Solution

Update the affected dhcp packages.
