The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2013:1801 :
Updated kernel packages that fix multiple security issues, several
bugs, and add two enhancements 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.
The kernel packages contain the Linux kernel, the core of any Linux
* A flaw was found in the way the Linux kernel's TCP/IP protocol suite
implementation handled sending of certain UDP packets over sockets
that used the UDP_CORK option when the UDP Fragmentation Offload (UFO)
feature was enabled on the output device. A local, unprivileged user
could use this flaw to cause a denial of service or, potentially,
escalate their privileges on the system. (CVE-2013-4470, Important)
* A divide-by-zero flaw was found in the apic_get_tmcct() function in
KVM's Local Advanced Programmable Interrupt Controller (LAPIC)
implementation. A privileged guest user could use this flaw to crash
the host. (CVE-2013-6367, Important)
* A memory corruption flaw was discovered in the way KVM handled
virtual APIC accesses that crossed a page boundary. A local,
unprivileged user could use this flaw to crash the system or,
potentially, escalate their privileges on the system. (CVE-2013-6368,
* An information leak flaw in the Linux kernel could allow a local,
unprivileged user to leak kernel memory to user space. (CVE-2013-2141,
Red Hat would like to thank Hannes Frederic Sowa for reporting
CVE-2013-4470, and Andrew Honig of Google for reporting CVE-2013-6367
This update also fixes several bugs and adds two enhancements.
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 and add these
enhancements. The system must be rebooted for this update to take
