The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2011:0429 :
Updated kernel packages that fix multiple 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
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
This update fixes the following security issues :
* A missing boundary check was found in the dvb_ca_ioctl() function in
the Linux kernel's av7110 module. On systems that use old DVB cards
that require the av7110 module, a local, unprivileged user could use
this flaw to cause a denial of service or escalate their privileges.
* An inconsistency was found in the interaction between the Linux
kernel's method for allocating NFSv4 (Network File System version 4)
ACL data and the method by which it was freed. This inconsistency led
to a kernel panic which could be triggered by a local, unprivileged
user with files owned by said user on an NFSv4 share. (CVE-2011-1090,
* A NULL pointer dereference flaw was found in the Generic Receive
Offload (GRO) functionality in the Linux kernel's networking
implementation. If both GRO and promiscuous mode were enabled on an
interface in a virtual LAN (VLAN), it could result in a denial of
service when a malformed VLAN frame is received on that interface.
* A missing security check in the Linux kernel's implementation of the
install_special_mapping() function could allow a local, unprivileged
user to bypass the mmap_min_addr protection mechanism. (CVE-2010-4346,
* An information leak was found in the Linux kernel's task_show_regs()
implementation. On IBM S/390 systems, a local, unprivileged user could
use this flaw to read /proc/[PID]/status files, allowing them to
discover the CPU register values of processes. (CVE-2011-0710, Low)
* A missing validation check was found in the Linux kernel's
mac_partition() implementation, used for supporting file systems
created on Mac OS operating systems. A local attacker could use this
flaw to cause a denial of service by mounting a disk that contains
specially crafted partitions. (CVE-2011-1010, Low)

This update also fixes several bugs. Documentation for these bug fixes
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
