Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated kernel packages that fix several security issues are now
available for Red Hat Enterprise Linux 4.7 Extended Update Support.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issues :

* Michael Tokarev reported a flaw in the Realtek r8169 Ethernet driver
in the Linux kernel. This driver allowed interfaces using this driver
to receive frames larger than what could be handled. This could lead
to a remote denial of service or code execution. (CVE-2009-1389,
Important)

* Tavis Ormandy and Julien Tinnes of the Google Security Team reported
a flaw in the SOCKOPS_WRAP macro in the Linux kernel. This macro did
not initialize the sendpage operation in the proto_ops structure
correctly. A local, unprivileged user could use this flaw to cause a
local denial of service or escalate their privileges. (CVE-2009-2692,
Important)

* Tavis Ormandy and Julien Tinnes of the Google Security Team reported
a flaw in the udp_sendmsg() implementation in the Linux kernel when
using the MSG_MORE flag on UDP sockets. A local, unprivileged user
could use this flaw to cause a local denial of service or escalate
their privileges. (CVE-2009-2698, Important)

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.
