Windows updates make systems crash again

Last day, Microsoft released an update classified as urgent to resolve a critical bug created by another update.

This security flaw, dubbed “PrintNightmare,” was discovered last week and, according to the company, allows attackers to install malicious code on a computer, allowing user data to be visualized or modified, as well as to create new data. Accounts with administrator privileges.

Hence, it is recommended for all users of Windows 10, Windows Server 2019, Windows Server 2012 R2, Windows Server 2008, Windows 8.1 and even Windows 7 to fix PrintNightmare.

This bug, called PrintNightmare, targets the Windows Print Spooler, which does not allow communication between the device and the printer.

Diverse Security Investigators He claimed that there was a vulnerability in this technology that would, in theory, allow a malicious hacker to infiltrate the system’s print spooler in order to grant administrator rights on a Windows PC.

As we already mentioned, according to Microsoft, all versions of Windows are vulnerable to PrintNightmare, but not all systems have access to patch files. Version 1607 of Windows 10, Windows Server 2016, and Windows Server 2012 still need patches — and Microsoft has promised to release these updates “soon.” If this update is not available in your operating system, Microsoft suggests disabling the Print Spooler manually until the error is corrected by the update.

“A few days ago, two security vulnerabilities were discovered in the Micrososft Windows print engine. These vulnerabilities allow a malicious attacker to take full control of all Windows environments that allow printing. This is an environment that consists primarily of workstations, but also sometimes affects servers that are an integral part of of enterprise computer networks.Microsoft categorized these vulnerabilities as critical, but when it was deployed only one of them could be resolved, leaving open the door to exploit the second vulnerability.This is why Microsoft advises all companies to remove their print jobs,which leads us An extreme and rare measure. Today, Microsoft has released a patch for the second vulnerability, allowing us to completely solve this problem. All Windows users, consumers and businesses, to check it out if they have systems in place, said Yaniv Palmas, Head of Cyber ​​Reseach at Check Point Software Technologies. Their operating system with the latest security updates recommended by Microsoft Active.
