  script_tag(name:"insight", value:"The Dynamic Host Configuration Protocol (DHCP) is a protocol that allows
individual devices on an IP network to get their own network configuration
information, including an IP address, a subnet mask, and a broadcast
address. The dhcp packages provide a relay agent and ISC DHCP service
required to enable and administer DHCP on a network.

Security Fix(es):

  * A command injection flaw was found in the NetworkManager integration
script included in the DHCP client packages in Red Hat Enterprise Linux. A
malicious DHCP server, or an attacker on the local network able to spoof
DHCP responses, could use this flaw to execute arbitrary commands with root
privileges on systems using NetworkManager and configured to obtain network
configuration using the DHCP protocol. (CVE-2018-1111)

Red Hat would like to thank Felix Wilhelm (Google Security Team) for
reporting this issue.");
