Microsoft releases critical patch

Microsoft on Monday released a critical patch outside of its normal patching cycle. 

The update fixes a vulnerability in Windows that could allow an attacker to execute code on a system if they can convince the user to open a specially crafted document, or have them visit an untrusted webpage that contains embedded OpenType fonts. 

The update, which requires a system reboot, was released to all UAB IT Desktop-supported machines at 4 p.m. Monday. Users have 72 hours to let the patch install and reboot the system. Users should get a notification bubble pop up at the system tray. After 72 hours, if a user has not allowed the patch to install, it will install automatically and the system will be forced to reboot.

UAB IT urges users to find an opportune time to let the patch install and allow the reboot occur to help protect UAB systems and information.
