Red Hat Security Advisory 2015-1741-01 – 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. All haproxy users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
