The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2013:0168 :
Updated kernel packages that fix three security issues and several
bugs are now available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having
moderate 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
This update fixes the following security issues :
* It was found that the Xen hypervisor implementation did not perform
range checking on the guest provided values in multiple hypercalls. A
privileged guest user could use this flaw to trigger long loops,
leading to a denial of service (Xen hypervisor hang). (CVE-2012-5515,
* It was found that when running a 32-bit binary that uses a large
number of shared libraries, one of the libraries would always be
loaded at a predictable address in memory. An attacker could use this
flaw to bypass the Address Space Layout Randomization (ASLR) security
feature. (CVE-2012-1568, Low)
* A flaw was found in the way the Linux kernel's IPv6 implementation
handled overlapping, fragmented IPv6 packets. A remote attacker could
potentially use this flaw to bypass protection mechanisms (such as a
firewall or intrusion detection system (IDS)) when sending network
packets to a target system. (CVE-2012-4444, Low)
Red Hat would like to thank the Xen project for reporting
CVE-2012-5515, and Antonios Atlasis working with Beyond Security's
SecuriTeam Secure Disclosure program and Loganaden Velvindron of
AFRINIC for reporting CVE-2012-4444.
This update also fixes several bugs. Space precludes documenting all
of these changes in this advisory. Documentation for these changes
will be available shortly from the Red Hat Enterprise Linux 5.9
Technical Notes document linked to in the References section.
Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect.
