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)

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.
