Ubuntu Security Notice USN-2715-1
August 18, 2015

linux-lts-trusty vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS

Summary:

The system could be made to crash under certain conditions.

Software Description:
- linux-lts-trusty: Linux hardware enablement kernel from Trusty

Details:

Marcelo Ricardo Leitner discovered a race condition in the Linux kernel's
SCTP address configuration lists when using Address Configuration Change
(ASCONF) options on a socket. An unprivileged local user could exploit this
flaw to cause a denial of service (system crash).

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
linux-image-3.13.0-62-generic 3.13.0-62.102~precise1
linux-image-3.13.0-62-generic-lpae 3.13.0-62.102~precise1

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
