Microsoft Windows is prone to a remote denial-of-service vulnerability that occurs in the Windows kernel ‘Win32k.sys’ kernel-mode device driver. A remote attacker can exploit this issue to crash the Windows kernel, denying service to legitimate users.
Block external access at the network boundary, unless external parties require service.
If global access isn’t needed, block access at the network perimeter to computers hosting the vulnerable operating system.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity such as unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.
Do not use client software to access unknown or untrusted hosts from critical systems.
To limit the risk of exploits, never connect to unknown or untrusted services.
Vendor updates are available. Please see the references for more information.
