Ubuntu Security Notice USN-3218-1
March 07, 2017

linux, linux-ti-omap4 vulnerability
==========================================================================

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

– Ubuntu 12.04 LTS

Summary:

The system could be made to crash or run programs as an administrator.

Software Description:
– linux: Linux kernel
– linux-ti-omap4: Linux kernel for OMAP4

Details:

Alexander Popov discovered that the N_HDLC line discipline implementation
in the Linux kernel contained a double-free vulnerability. A local attacker
could use this to cause a denial of service (system crash) or possibly gain
administrative privileges.

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-124-generic 3.2.0-124.167
linux-image-3.2.0-124-generic-pae 3.2.0-124.167
linux-image-3.2.0-124-highbank 3.2.0-124.167
linux-image-3.2.0-124-omap 3.2.0-124.167
linux-image-3.2.0-124-powerpc-smp 3.2.0-124.167
linux-image-3.2.0-124-powerpc64-smp 3.2.0-124.167
linux-image-3.2.0-124-virtual 3.2.0-124.167
linux-image-3.2.0-1502-omap4 3.2.0-1502.129
linux-image-generic 3.2.0.124.139
linux-image-generic-pae 3.2.0.124.139
linux-image-highbank 3.2.0.124.139
linux-image-omap 3.2.0.124.139
linux-image-omap4 3.2.0.1502.97
linux-image-powerpc-smp 3.2.0.124.139
linux-image-powerpc64-smp 3.2.0.124.139
linux-image-virtual 3.2.0.124.139

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.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
