Ubuntu Security Notice USN-3082-1
September 19, 2016

linux vulnerability
==========================================================================

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

– Ubuntu 12.04 LTS

Summary:

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

Software Description:
– linux: Linux kernel

Details:

Chiachih Wu, Yuan-Tsung Lo, and Xuxian Jiang discovered that the legacy ABI
for ARM (OABI) had incomplete access checks for epoll_wait(2) and
semtimedop(2). A local attacker could use this to possibly execute
arbitrary code.

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-110-generic 3.2.0-110.151
linux-image-3.2.0-110-generic-pae 3.2.0-110.151
linux-image-3.2.0-110-highbank 3.2.0-110.151
linux-image-3.2.0-110-omap 3.2.0-110.151
linux-image-3.2.0-110-powerpc-smp 3.2.0-110.151
linux-image-3.2.0-110-powerpc64-smp 3.2.0-110.151
linux-image-3.2.0-110-virtual 3.2.0-110.151

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.
