INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Ubuntu 12.04 Precise
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

* Improved fix for CVE-2016-3134: Memory corruption when parsing netfilter source chains.

A logic error when parsing netfilter source chains can allow local users
to corrupt kernel memory.


* CVE-2016-3961: Xen PV guest crash when using HugeTLBFS.

HugeTLBFS is not supported on Xen PV guests and leads to a kernel crash
when an application tries to mmap() a Huge TLB.  A local user with the
ability to mmap() Huge TLB pages in a Xen PV guest can cause a
denial-of-service of the guest.


* CVE-2016-4470: Kernel panic when adding a negative key to a keyring.

A logic error in the kernel keyring subsystem can cause a write to an
uninitialized pointer which can trigger kernel memory corruption and a
kernel panic.


* CVE-2016-5243: Information leak in the Transparent Inter Process Communication protocol.

The use of strcpy() inside the Transparant Inter Process Communication
protocol (TIPC) when dumping the link name leads to a maximum of 58 bytes
leaked to userspace.  A local attacker could use this flaw to gain
information about the running kernel and facilitate an attack.
