The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2013:1051 :
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 flaw was found in the tcp_read_sock() function in the Linux
kernel's IPv4 TCP/IP protocol suite implementation in the way socket
buffers (skb) were handled. A local, unprivileged user could trigger
this issue via a call to splice(), leading to a denial of service.
* Information leak flaws in the Linux kernel could allow a local,
unprivileged user to leak kernel memory to user-space. (CVE-2012-6548,
CVE-2013-2634, CVE-2013-2635, CVE-2013-3222, CVE-2013-3224,
* An information leak was found in the Linux kernel's POSIX signals
implementation. A local, unprivileged user could use this flaw to
bypass the Address Space Layout Randomization (ASLR) security feature.
* A format string flaw was found in the ext3_msg() function in the
Linux kernel's ext3 file system implementation. A local user who is
able to mount an ext3 file system could use this flaw to cause a
denial of service or, potentially, escalate their privileges.
* A format string flaw was found in the b43_do_request_fw() function
in the Linux kernel's b43 driver implementation. A local user who is
able to specify the 'fwpostfix' b43 module parameter could use this
flaw to cause a denial of service or, potentially, escalate their
privileges. (CVE-2013-2852, Low)
* A NULL pointer dereference flaw was found in the Linux kernel's
ftrace and function tracer implementations. A local user who has the
CAP_SYS_ADMIN capability could use this flaw to cause a denial of
service. (CVE-2013-3301, Low)
Red Hat would like to thank Kees Cook for reporting CVE-2013-2852.
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. The system must be
rebooted for this update to take effect.
