[Sonja Tideman]

Synopsis: 2.6.32-042stab076.8 can now be patched using Ksplice
CVEs: CVE-2013-2094

Systems running Virtuozzo 4.7 or the OpenVZ RHEL 6 kernel can now use
Ksplice to patch against the latest Parallels Virtuozzo Containers 4.7
kernel security update, 2.6.32-042stab076.8.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Virtuozzo 4.7 or
OpenVZ on RHEL 6 install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2013-2094: Out-of-bounds memory write in perf_event_open() system 
call.

Due to implicit integer truncation, an unprivileged user can corrupt
kernel memory by passing an invalid value to the perf_event_open()
system call, possibly leading to denial of service or privilege
escalation.
