Ubuntu Security Notice USN-3218-1

7th March, 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 version:

Ubuntu 12.04 LTS:
linux-image-omap4 3.2.0.1502.97
linux-image-3.2.0-124-virtual

3.2.0-124.167

3.2.0-1502.129
linux-image-omap 3.2.0.124.139
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

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.

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.
