Summary
Red Hat Security Advisory: haproxy security update

Notes

Topic
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.
Details
HAProxy provides high availability, load balancing, and proxying for TCP and HTTP-based applications. An implementation error related to the memory management of request 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) All haproxy users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
