linux vulnerabilities

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

Ubuntu 14.04 LTS

Summary

Several security issues were fixed in the kernel.

Software description

linux
– Linux kernel

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. (CVE-2016-7425)

Daxing Guo discovered a stack-based buffer overflow in the Broadcom
IEEE802.11n FullMAC driver in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash) or possibly gain
privileges. (CVE-2016-8658)

Update instructions

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

Ubuntu 14.04 LTS:: linux-image-powerpc-smp

3.13.0.103.111; linux-image-powerpc-e500mc

3.13.0.103.111; linux-image-3.13.0-103-powerpc-e500

3.13.0-103.150; linux-image-3.13.0-103-generic

3.13.0-103.150; linux-image-generic

3.13.0.103.111; linux-image-3.13.0-103-generic-lpae

3.13.0-103.150; linux-image-3.13.0-103-powerpc64-emb

3.13.0-103.150; linux-image-3.13.0-103-powerpc-smp

3.13.0-103.150; linux-image-3.13.0-103-powerpc-e500mc

3.13.0-103.150; linux-image-3.13.0-103-lowlatency

3.13.0-103.150; linux-image-powerpc64-smp

3.13.0.103.111; linux-image-generic-lpae

3.13.0.103.111; linux-image-lowlatency

3.13.0.103.111; linux-image-omap

3.13.0.103.111; linux-image-powerpc64-emb

3.13.0.103.111; linux-image-3.13.0-103-powerpc64-smp

3.13.0-103.150

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.
