Detail
Problem Description: An update for keepalived 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Server (v. 7) - ppc64le, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server (v. 7) - aarch64, ppc64le 3. Description: The keepalived utility provides simple and robust facilities for load balancing and high availability. The load balancing framework relies on the well-known and widely used IP Virtual Server (IPVS) kernel module providing layer-4 (transport layer) load balancing. Keepalived implements a set of checkers to dynamically and adaptively maintain and manage a load balanced server pool according to the health of the servers. Keepalived also implements the Virtual Router Redundancy Protocol (VRRPv2) to achieve high availability with director failover. Security Fix(es): * keepalived: Heap-based buffer overflow when parsing HTTP status codes allows for denial of service or possibly arbitrary code execution (CVE-2018-19115) 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. 4.
