[Announce] Kernel RHEL6 testing 042stab076.5

[Kir Kolyshkin]

OpenVZ project has released an updated RHEL6 based testing kernel. Read 
below for more information.

NOTE that this is a *testing* kernel, not yet recommended for production.

Changes
=======
Since 042stab076.3:

This kernel is still based on 2.6.32-279.22.1.el6 Red Hat kernel, but a 
set of security patches has been backported from 
kernel-2.6.32-358.2.1.el6 RHEL6.4 kernel (RHSA-2013-0630):

* A flaw was found in the way the xen_iret() function in the Linux 
kernel used the DS (the CPU's Data Segment) register. A local, 
unprivileged user in a 32-bit, para-virtualized Xen hypervisor guest 
could use this flaw to crash the guest or, potentially, escalate their 
privileges. (CVE-2013-0228, Important)

* A flaw was found in the way file permission checks for the 
"/dev/cpu/[x]/msr" files were performed in restricted root environments 
(for example, when using a capability-based security model). A local 
user with the ability to write to these files could use this flaw to 
escalate their privileges to kernel level, for example, by writing to 
the SYSENTER_EIP_MSR register. (CVE-2013-0268, Important)
