The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2014:0475 :
Updated kernel packages that fix three security issues and several
bugs are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having
Important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

* A flaw was found in the way the Linux kernel's netfilter connection
tracking implementation for Datagram Congestion Control Protocol
(DCCP) packets used the skb_header_pointer() function. A remote
attacker could use this flaw to send a specially crafted DCCP packet
to crash the system or, potentially, escalate their privileges on the
system. (CVE-2014-2523, Important)
* A flaw was found in the way the Linux kernel's Adaptec RAID
controller (aacraid) checked permissions of compat IOCTLs. A local
attacker could use this flaw to bypass intended security restrictions.
* A flaw was found in the way the handle_rx() function handled large
network packets when mergeable buffers were disabled. A privileged
guest user could use this flaw to crash the host or corrupt QEMU
process memory on the host, which could potentially result in
arbitrary code execution on the host with the privileges of the QEMU
process. (CVE-2014-0077, Moderate)
The CVE-2014-0077 issue was discovered by Michael S. Tsirkin of Red
This update also fixes several bugs. Documentation for these changes
will be available shortly from the Technical Notes document linked to
in the References section.
All kernel users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. The system
must be rebooted for this update to take effect.
