If you’re still using Windows Vista for some unknown reason, you’ll be happy to know that Microsoft recently released an update for the ancient operating system. The update is designed with security in mind with the issue deemed critical by Microsoft.

An excerpt of Microsoft’s security bulletin report:

This security update is rated Critical for all supported releases of Microsoft Windows. For more information, see the Affected Software and Vulnerability Severity Ratings section.

The update addresses the vulnerabilities by:

  • Correcting how the Windows Print Spooler service writes to the file system
  • Issuing a warning to users who attempt to install untrusted printer drivers

If you’re logged in an as administrator, you will be at greater risk from any possible attack. Furthermore, an attacker could take advantage of the flaw by targeting a print server or system. The attacker would then inject a malicious code and then sit back as things fall apart.

Why is this even possible? Well, the print spooler doesn’t properly validate printer drivers when they are being installed.

Here’s what Vectra Networks security researcher, Nicolas Beauchesne, had to say:

Normally, User Account Controls are in place to warn or prevent a user from installing a new driver. To make printing easier, an exception was created to avoid this control,” he said. “So in the end, we have a mechanism that allows downloading executables from a shared drive, and run them as system on a workstation without generating any warning on the user side. From an attacker perspective, this is almost too good to be true, and of course we had to give it a try.”

Keep this issue in mind and an eye out for the update.
