canta gtk themeIf your current Ubuntu desktop is looking a little dark and a little dated why not give it a refresh? And the perfect choice to help you do that is the Canta theme by serial theme maker Vince Liuice (of Vimix theme fame).

USN-3594-1: Linux kernel vulnerability

linux vulnerability

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

  • Ubuntu 14.04 LTS

Summary

The system could be made to expose sensitive information.

Software Description

  • linux – Linux kernel

Details

USN-3542-1 mitigated CVE-2017-5715 (Spectre Variant 2) for the
amd64 architecture in Ubuntu 14.04 LTS. This update provides the
compiler-based retpoline kernel mitigation for the amd64 and i386
architectures. Original advisory details:

Jann Horn discovered that microprocessors utilizing speculative execution
and branch prediction may allow unauthorized memory reads via sidechannel
attacks. This flaw is known as Spectre. A local attacker could use this to
expose sensitive information, including kernel memory. (CVE-2017-5715)

Update instructions

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

Ubuntu 14.04 LTS
linux-image-3.13.0-143-generic3.13.0-143.192
linux-image-3.13.0-143-generic-lpae3.13.0-143.192
linux-image-3.13.0-143-lowlatency3.13.0-143.192
linux-image-generic3.13.0.143.153
linux-image-generic-lpae3.13.0.143.153
linux-image-lowlatency3.13.0.143.153

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.
