Microsoft has just released a new patch, and this time, the update comes with fixes for several dangerous and actively abused vulnerabilities and exploits in Windows.
A total of 68 vulnerabilities were addressed in the patch, many of them critical. Here’s what’s fixed and how to make sure your Windows device is up to date.
Microsoft regularly releases updates for Windows 11 and Windows 10, but this time, it seems to have addressed a whole host of urgent issues that could have put your computer at risk. As part of this month’s Patch Tuesday, a total of 68 bugs were fixed, and 11 of them are classified as critical. According to bleeping computerthose critical flaws allowed potential attackers to remotely execute malicious code, as well as elevated privileges, within the system.
Broken down into various categories, Microsoft’s latest update contains 27 vulnerabilities related to elevation of privilege, 16 that allowed remote code execution, 11 that disclosed information, six denial of service vulnerabilities, four that allow an attacker to bypass security features, security and three related to identity theft.
Perhaps most importantly, the patch fixes six zero-day vulnerabilities that were being actively exploited. According to Microsoft’s classification, a vulnerability is known as “zero-day” if it is actively exploited and/or known to the public, but does not yet have an official fix.
The first of the exploits required users with an affected version of Windows to access a specific server. While there would be no way for the attacker to run this exploit without the victim visiting a malicious server or website, once they did, the hacker would gain remote code execution privileges. Another vulnerability gave attackers the ability to bypass Mark of the Web (MOTW) defenses, resulting in an unavailability of several security features, including Protected View in Microsoft Office.
A couple of the other zero-day vulnerabilities granted system privileges, and that can lead to a complete loss of control over your PC. You can check out a full list of fixed issues here, courtesy of bleeping computer.
All in all, this looks like a patch you don’t want to miss. The update should roll out for Windows users, and whether you’re using Windows 11 or Windows 10, you can head over to your Windows Update and download it.
