Microsoft PostScript and PCL6 printer drivers were found to have a vulnerability that could allow hackers to remotely execute code on computers. The vulnerability received a CVSS score of 8.8 out of 10, meaning it is considered highly severe.

The vulnerability affects how Microsoft printer drivers process PostScript and PCL6 print files. By crafting a malicious file, hackers could potentially execute code of their choice on the computer. This would allow them to install programs, view, change or delete data, or create new accounts with full user rights.

To exploit the vulnerability, a hacker would need to trick a user into printing a malicious file design to exploit the vulnerability. This could be done through a phishing email attachment or link. Simply connecting to a public printer could also potentially put users at risk if that printer was under a hacker’s control.

The best way to protect yourself is to make sure your Microsoft printer drivers are up-to-date. Microsoft has released security updates to address this issue, so ensuring automatic updates are enabled is important. You should also be cautious about opening unexpected file attachments or links, especially for printing. Connecting only to printers you trust can reduce risks as well. Staying on top of software updates is one of the best ways to defeat hackers looking for vulnerabilities to exploit.
