Uncover solutions for various flaws affecting the Ubuntu Trusty HWE kernel, safeguarding both system integrity and performance.
Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

- linux-lts-trusty: Linux hardware enablement kernel from Trusty for Precise

Details:

USN-3145-1 fixed vulnerabilities in the Linux kernel for Ubuntu

14.04 LTS. This update provides the corresponding updates for the

Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for

Ubuntu 12.04 LTS.

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 12.04 LTS:
  linux-image-3.13.0-103-generic  3.13.0-103.150~precise1
  linux-image-3.13.0-103-generic-lpae  3.13.0-103.150~precise1
  linux-image-generic-lpae-lts-trusty  3.13.0.103.94
  linux-image-generic-lts-trusty  3.13.0.103.94

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.
