Over the past few days, you may have heard of the new vulnerabilities that has been uncovered, Meltdown and Spectre. These vulnerabilities affect all modern processors, meaning your business machines and even personal gadgets that use processors are affected which puts you in risk of potential attacks. Below is a brief explanation of what exactly Meltdown and Spectre are:
Meltdown is a hardware vulnerability in processors (Intel x86 microprocessors and some ARM based microprocessors) which allows attackers to use programs to access your computer’s memory. With this access, they are able to gain sensitive data from your other applications within your system.
Spectre is a hardware vulnerability in modern processors, which attackers can use to trick error-free programs, which follow best practices, into leaking their secrets. Safety checks of said best practices actually increase the attack surface and may make applications more susceptible to Spectre.
However, since the vulnerability has been announced it means that so have the solutions. Below are the steps in which you need to take fix these vulnerabilities:
1. Update your Processor Firmware
Processor manufacturers have already released firmware updates to fix these vulnerabilities, however they said that they would only be releasing updates for processors within the last 5 years. Below are the current firmware updates you will need per vendor (note that we will be placing more updates as they come):

2. Checking if your registry is compatible with your OS updates (Windows)
There are some third party anti-virus software that are currently incompatible with the latest patch updates from Windows. If you are unable to update your OS due to this reason, it is recommended that you modify your registry to fix this. However we highly recommend that you also backup your registry before you manually edit it as using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Below is the registry key to be set:
For Trend Micro users, there has been a patch release for their products in which enables the ALLOW REGKEY (the above code) automatically. This however is not the fix to the vulnerabilities and you have to update your OS as this patch will not update your OS but allow you to update.
Additionally, note that per Microsoft, even clients that do not have active anti-malware or security software installed may still be required to apply the specific registry key before the security patches can be obtained from Windows Update.
3. Updating your OS (Operating System)
Below are the updates that are currently out for Windows OS for both Servers and Desktop (this will be updated as more updates are released):
4. Updating your browsers
The last step would be to make sure that your internet browser is patched to the latest version. Below are a few of the most used browsers and the versions they need to be updated to:
Mozilla – Firefox 57.0.4
Internet Explorer/Microsoft Edge – Included in the latest security update of Windows KB4056890 (OS Build 14393.2007)
Again more updates will be posted as soon as the fixes are released by the respective vendors. If you need more details or help in implementing the said solutions from vendors, please do contact us at 893-9515 and we will do our utmost to help!
