dhcp-4.2.5-47.0.1.el7.AXS7
Affected Channels: 
Asianux Server 7 for x86_64
Severity: 
Moderate
Description: 

DHCP (Dynamic Host Configuration Protocol) is a protocol which allows
individual devices on an IP network to get their own network
configuration information (IP address, subnetmask, broadcast address,
etc.) from a DHCP server. The overall purpose of DHCP is to make it
easier to administer a large network.

To use DHCP on your network, install a DHCP service (or relay agent),
and on clients run a DHCP client daemon. The dhcp package provides
the ISC DHCP service and relay agent.

Security issues fixed with this release:

CVE-2016-2774
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.

Additional Changes:

Solution: 

Update packages.

CVEs:
