An update for dhcp is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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) :

* dhcp: Buffer overflow in dhclient possibly allowing code execution triggered by malicious server (CVE-2018-5732)

* dhcp: Reference count overflow in dhcpd allows denial of service (CVE-2018-5733)

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Red Hat would like to thank ISC for reporting these issues. Upstream acknowledges Felix Wilhelm (Google) as the original reporter of these issues.
