The remote Red Hat host is missing one or more security updates.


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

Note that, according to CVE-2015-3281, this issue only exists in HAProxy version 1.5.x prior to 1.5.14. All HAProxy users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.


Update the affected haproxy and / or haproxy-debuginfo packages.
