[Ksplice][Virtuozzo 4.7 Updates] New updates available via Ksplice (CU-2.6.32-042stab078.22)

[Jamie Iles]

Synopsis: CU-2.6.32-042stab078.22 can now be patched using Ksplice

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, CU-2.6.32-042stab078.22.

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

* Denial of service in try_to_release_page().

An incomplete check could cause try_to_release_page() to be called for
swap-backed pages which results in a kernel BUG.  This could be exploited
by a local user to cause a denial of service.
