The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2012:1426 :
Updated kernel packages that fix multiple 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
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 :
* A use-after-free flaw was found in the Linux kernel's memory
management subsystem in the way quota handling for huge pages was
performed. A local, unprivileged user could use this flaw to cause a
denial of service or, potentially, escalate their privileges.
* A use-after-free flaw was found in the madvise() system call
implementation in the Linux kernel. A local, unprivileged user could
use this flaw to cause a denial of service or, potentially, escalate
their privileges. (CVE-2012-3511, Moderate)
* 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)
* Buffer overflow flaws were found in the udf_load_logicalvol()
function in the Universal Disk Format (UDF) file system implementation
in the Linux kernel. An attacker with physical access to a system
could use these flaws to cause a denial of service or escalate their
privileges. (CVE-2012-3400, Low)
Red Hat would like to thank Shachar Raindel for reporting
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.
Users should upgrade to these updated packages, which contain
backported patches to correct these issues, and fix the bugs noted in
the Technical Notes. The system must be rebooted for this update to
