Synopsis :

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

Description :

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.
