USN-3144-2: Linux kernel (OMAP4) vulnerability

Ubuntu Security Notice USN-3144-2

30th November, 2016

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 under certain conditions.

Software description

• linux-ti-omap4 - Linux kernel for OMAP4

Details

Marco Grassi discovered that the driver for Areca RAID Controllers in the
Linux kernel did not properly validate control messages. A local attacker
could use this to cause a denial of service (system crash) or possibly gain
privileges.

Update instructions

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

Ubuntu 12.04 LTS:

linux-image-omap4 3.2.0.1494.89

linux-image-3.2.0-1494-omap4 3.2.0-1494.121

To update your system, please follow these instructions: http://ift.tt/17VXqjU.

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.
