On July 13, Microsoft released additional updates offering further protection from the PrintNightmare vulnerability. Please ensure that you have installed these latest updates from Microsoft on your personal Windows devices that are used to connect to the Fermilab network. The original announcement posted on July 9 is included below, which has instructions on how to install Microsoft updates.
WHAT ARE WE DOING?
Over the past week, a serious security vulnerability for Windows devices has been discovered. It is called PrintNightmare and it utilizes a bug in the Windows printing components to allow an attacker to gain access to the device. Fermilab has already implemented mitigations to protect Fermilab-owned equipment, but Computing is also asking users to ensure they have patched their personal Windows devices that are used to connect to the Fermilab network.
WHAT IS THE IMPACT TO YOU?
Computing asks that you ensure you have installed the latest patches that have been released to your non-Fermilab-owned Windows devices.
WHAT DO YOU NEED TO DO?
Follow these steps to install Microsoft’s patch to fix the problematic bug:
- Select the Start menu (Windows icon).
- Select Settings > Update & Security > Windows Update.
- Install any updates listed.
It is possible that the patch has already been installed on your system. If no updates are listed, that is likely the case.
