Synopsis: 2.6.32-379.5.1.lve1.1.9.6.1 can now be patched using Ksplice
CVEs: CVE-2011-1078 CVE-2012-2384

Systems running CloudLinux 6 can now use Ksplice to patch against the
latest CloudLinux 6 kernel update, 2.6.32-379.5.1.lve1.1.9.6.1.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on CloudLinux 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

* Unreliable futexes with read-only shared mappings.

Futex operations on read-only memory maps did not work correctly,
breaking workloads that had one or more reader processes performing the
FUTEX_WAIT operation on a futex within a read-only shared file mapping
and a writer process that had a writable mapping performing the
FUTEX_WAKE operation.


* CVE-2011-1078: Information leak in Bluetooth SCO link driver.

One byte of the 'struct sco_conninfo' data structure was not
initialized before being copied to userspace, leading to a leak of
potentially sensitive kernel memory.


* CVE-2012-2384: Integer overflow in i915 execution buffer.

An integer overflow in the i915 execution buffer code could result in a
user triggering a denial-of-service attack or elevating privileges.


* NULL pointer dereference in non-persistent tunnel devices.

A NULL pointer dereference in the tunneling network device may occur
when closing a tunnel device.
