Ubuntu Security Notice USN-3145-1
November 30, 2016

linux vulnerabilities

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

- Ubuntu 14.04 LTS


Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel


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 versions:

Ubuntu 14.04 LTS:
  linux-image-3.13.0-103-generic  3.13.0-103.150
  linux-image-3.13.0-103-generic-lpae  3.13.0-103.150
  linux-image-3.13.0-103-lowlatency  3.13.0-103.150
  linux-image-3.13.0-103-powerpc-e500  3.13.0-103.150
  linux-image-3.13.0-103-powerpc-e500mc  3.13.0-103.150
  linux-image-3.13.0-103-powerpc-smp  3.13.0-103.150
  linux-image-3.13.0-103-powerpc64-emb  3.13.0-103.150
  linux-image-3.13.0-103-powerpc64-smp  3.13.0-103.150

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.

  CVE-2016-7425, CVE-2016-8658
