Systems running CloudLinux 6 can now use Ksplice to patch against the
latest CloudLinux 6 kernel update, 2.6.32-379.11.1.lve1.1.9.8.2.el6.

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

* CVE-2012-2384: Integer overflow in Intel i915 command processing.

An integer overflow in the Intel i915 family display driver could cause 
memory
corruption on 32-bit systems.


* CVE-2012-2390: Memory leak in hugetlbfs mmap() failure.

Incorrect error handling in the mmap() implementation for hugetlbfs
could result in reservations not being freed resulting in a denial of
service.


* CVE-2012-2313: Privilege escalation in the dl2k NIC.

The D-LINK dl2k network card was missing permission checks in the ioctl
handling function. This would allow an unprivileged user to reconfigure
the low-level link device and trigger a denial-of-service.


* CVE-2012-3430: kernel information leak in RDS sockets.

Calling recvfrom() on an RDS socket could result in leaking the contents
of kernel stack memory to userspace.


* CVE-2012-3552: Denial-of-service in IP options handling.

Missing locking around IP options for a socket could allow an attacker
to trigger a use-after-free condition resulting in a kernel crash.
Under certain conditions this could be exploitable by a remote user.


* 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.
