Two far-reaching vulnerabilities discovered in all modern CPUs

In the last two days, information about new massive vulnerabilities in all current processors for computer systems has been published in advance.
Slowly, more details are recognizable by the first reactions from e.g. Intel and Google. It can be assumed that in the next few days even more details will come through.
The two possible attack scenarios have been named "Spectre" and "Meltdown". At the moment no active attacks or the exploitation of the vulnerability are known.

In principle, all current systems are affected - servers, personal computers, tablets and smartphones. Depending on the scope and possible scenarios, all manufacturers such as Intel, AMD and ARM are affected.
The impact on Intel systems seems to be greater, AMD systems are less vulnerable. There is still no agreement on the actual effects and whether these weak points are already being exploited.

Hardware manufacturers are already making efforts to develop necessary software patches with the various operating system manufacturers.

For Android systems there is already an update available with the security update from 02. January 2018. It’s to be expected that the respective manufacturers will take over this patch and also the users will install this update.

Virus scanners must explicitly confirm compatibility with the operating system before Microsoft Windows installs the security update.

IKARUS is currently reviewing the compatibility of its products extensively and will release an update next week confirming this compatibility.

Customers who would like to receive the Microsoft Update beforehand can activate this at their own risk via a registry switch. Information about this can be found here:
