Test ID:1.3.6.1.4.1.25623.1.0.71922
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2012:1150
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2012:1150.

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

This update fixes the following security issues:

* A memory leak flaw was found in the way the Linux kernel's memory
subsystem handled resource clean up in the mmap() failure path when the
MAP_HUGETLB flag was set. A local, unprivileged user could use this flaw to
cause a denial of service. (CVE-2012-2390, Moderate)

* A flaw was found in the way the Linux kernel's Event Poll (epoll)
subsystem handled resource clean up when an ELOOP error code was returned.
A local, unprivileged user could use this flaw to cause a denial of
service. (CVE-2012-3375, Moderate)

This update also fixes the following bugs:

* The MRG 2.1 realtime kernel lacked support for automatic memory
reservation for the kdump kernel, as present in Red Hat Enterprise Linux
kernels. Using the parameter crashkernel=auto on the kernel boot command
line led to kdump being disabled because no memory was correctly reserved.
Support for crashkernel=auto has been implemented in the 3.0 realtime
kernel and now when the crashkernel=auto parameter is specified, machines
with more than 4GB of RAM have the amount of memory required by the kdump
kernel calculated and reserved. (BZ#820427)

* The current bnx2x driver in the MRG 2.1 realtime kernel had faulty
support for the network adapter PCI ID 14e4:168e and did not work
correctly. The bnx2x driver was updated to include support for this network
adapter. (BZ#839037)

Users should upgrade to these updated packages, which upgrade the kernel-rt
kernel to version kernel-rt-3.0.36-rt57, and correct these issues. The
system must be rebooted for this update to take effect.

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
