[Jamie Iles]

Synopsis: CU-2.6.32-042stab063.2 can now be patched using Ksplice
CVEs: CVE-2012-3412

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-2.6.32-042stab063.2.

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-2012-3412: Remote denial of service through TCP MSS option in SFC NIC.

A malicious remote user may trigger a denial-of-service in hosts using the SFC
NIC by reducing the size of the TCP MSS and causing the victim to run out
of resources while processing the packets.


* Kernel panic in TTY driver.

An invalid assumption in the TTY driver can lead to a kernel
panic (BUG_ON) when reading data from a TTY using the normal
line discipline.
