The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2015:1081 :
Updated kernel packages that fix multiple security issues, several
bugs, and add various enhancements are now available for Red Hat
Enterprise Linux 6.
Red Hat Product Security 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
* It was found that the Linux kernel's implementation of vectored pipe
read and write functionality did not take into account the I/O vectors
that were already processed when retrying after a failed atomic access
operation, potentially resulting in memory corruption due to an I/O
vector array overrun. A local, unprivileged user could use this flaw
to crash the system or, potentially, escalate their privileges on the
system. (CVE-2015-1805, Important)
* A buffer overflow flaw was found in the way the Linux kernel's Intel
AES-NI instructions optimized version of the RFC4106 GCM mode
decryption functionality handled fragmented packets. A remote attacker
could use this flaw to crash, or potentially escalate their privileges
on, a system over a connection with an active AES-GCM mode IPSec
security association. (CVE-2015-3331, Important)
* An information leak flaw was found in the way the Linux kernel
changed certain segment registers and thread-local storage (TLS)
during a context switch. A local, unprivileged user could use this
flaw to leak the user space TLS base address of an arbitrary process.
* It was found that the Linux kernel's ISO file system implementation
did not correctly limit the traversal of Rock Ridge extension
Continuation Entries (CE). An attacker with physical access to the
system could use this flaw to trigger an infinite loop in the kernel,
resulting in a denial of service. (CVE-2014-9420, Low)
* An information leak flaw was found in the way the Linux kernel's
Virtual Dynamic Shared Object (vDSO) implementation performed address
randomization. A local, unprivileged user could use this flaw to leak
kernel memory addresses to user-space. (CVE-2014-9585, Low)
Red Hat would like to thank Carl Henrik Lunde for reporting
CVE-2014-9420. The security impact of the CVE-2015-1805 issue was
discovered by Red Hat.
This update also fixes several bugs and adds various enhancements.
Documentation for these changes is available 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
