Security update for dhcp

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.

ISC DHCP 4.1.x before 4.1-ESV-R13 and 4.2.x and 4.3.x before 4.3.4 does not restrict the number of concurrent TCP sessions, which allows remote attackers to cause a denial of service (INSIST assertion failure or request-processing outage) by establishing many sessions.
