Synopsis

The remote CentOS host is missing a security update.

Description

An updated haproxy package that fixes one security issue is now available for Red Hat Enterprise Linux 6 and 7.

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

HAProxy provides high availability, load balancing, and proxying for TCP and HTTP-based applications.

An implementation error related to the memory management of requests and responses was found within HAProxy's buffer_slow_realign() function. An unauthenticated remote attacker could possibly use this flaw to leak certain memory buffer contents from a past request or session. (CVE-2015-3281)
