The update was released as soon as possible and outside the company's security updates due to the seriousness of the issue, which brought great relief to millions of businesses and consumers around the world who were trying to fix the problem.
The PrintNightmare zero-day exploit (CVE-2021-34527) is a remote code execution vulnerability. This means that an attacker could theoretically run some malicious code on the victim's system from a distance.
Η Microsoft released security updates to fix the problem, covering all active versions of Windows 10 (even some that are no longer active, such as Windows 10 version 1507), Windows 8.1 and Windows 7, which are also no longer supported.
But there are some exceptions, such as Windows 10 version 1607, Windows Server 2016 and Windows Server 2012, where the company will release the update later.
