CVE-2018-19115

Status Candidate

Overview

keepalived before 2.0.7 has a heap-based buffer overflow when parsing HTTP status codes resulting in DoS or possibly unspecified other impact, because extract_status_code in lib/html.c has no validation of the status code and instead writes an unlimited amount of data to the heap.

Red Hat Security Advisory 2019-0022-01
Posted Jan 3, 2019
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2019-0022-01 - 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 kernel module providing layer-4 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 to achieve high availability with director failover. Issues addressed include buffer overflow, code execution, and denial of service vulnerabilities.
