CPU security issue: Meltdown and Spectre

What we are doing and what you should do

Latest: 24 January 2018

Information Services are working hard to minimise the risk posed by Spectre and Meltdown CPU vulnerabilities. Please expect some disruption to services while we apply updates. You may also experience slower response times from IS teams and delays to one or two IS projects as we focus on the extra work involved.

Advice for your device

For your own devices (laptops, tablets, smartphones etc.) please keep the operating system and other software updated as you are prompted. Pay special attention to updates for web browsers.

If your device is no longer receiving security updates or is too old to support them then it needs to be replaced.

The BIOS/firmware will also need updating on many devices, however updates are still being finalised by CPU manufacturers. We’ll issue further advice once the situation is clearer.

You may have seen in the news that a vulnerability has been found which affects central processing units (CPUs) in many of the devices we all use.

Information Services are working hard to ensure that University Infrastructure is updated appropriately, and that any potential risks are mitigated.

We advise you to apply security updates for your own devices as you would normally. It is always important to keep your device updated with the latest security updates.

We will offer further advice as manufacturers respond to the issue. Further details and advice can be from the National Cyber Security Centre (NCSC) and on the BBC News website.
