The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2014:0108 :
Updated kernel packages that fix one security issue and three 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. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.
The kernel packages contain the Linux kernel, the core of any Linux
* It was found that the Xen hypervisor did not always lock
'page_alloc_lock' and 'grant_table.lock' in the same order. This could
potentially lead to a deadlock. A malicious guest administrator could
use this flaw to cause a denial of service on the host.
Red Hat would like to thank the Xen project for reporting this issue.
This update also fixes the following bugs :
* A recent patch to the CIFS code that introduced the NTLMSSP (NT LAN
Manager Security Support Provider) authentication mechanism caused a
regression in CIFS behavior. As a result of the regression, an
encryption key that is returned during the SMB negotiation protocol
response was only used for the first session that was created on the
SMB client. Any subsequent mounts to the same server did not use the
encryption key returned by the initial negotiation with the server. As
a consequence, it was impossible to mount multiple SMB shares with
different credentials to the same server. A patch has been applied to
correct this problem so that an encryption key or a server challenge
is now provided for every SMB session during the SMB negotiation
protocol response. (BZ#1029865)
* The igb driver previously used a 16-bit mask when writing values of
the flow control high-water mark to hardware registers on a network
device. Consequently, the values were truncated on some network
devices, disrupting the flow control. A patch has been applied to the
igb driver so that it now uses a 32-bit mask as expected. (BZ#1041694)
* The IPMI driver did not properly handle kernel panic messages.
Consequently, when a kernel panic occurred on a system that was
utilizing IPMI without Kdump being set up, a second kernel panic could
be triggered. A patch has been applied to the IPMI driver to fix this
problem, and a message handler now properly waits for a response to
panic event messages. (BZ#1049731)
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.
