Network & internet WORMS are among the most dangerous malware.  Only the true system patch, disabling services, or AV protection can prevent automatic infections.   Microsoft & other security firms are sharing the need to install AUG-2019 security patches on a priority basis.

Patch new wormable vulnerabilities in Remote Desktop Services (CVE-2019-1181/1182)

Today Microsoft released a set of fixes for Remote Desktop Services that include two critical Remote Code Execution (RCE) vulnerabilities, CVE-2019-1181 and CVE-2019-1182. Like the previously-fixed ‘BlueKeep’ vulnerability (CVE-2019-0708), these two vulnerabilities are also ‘wormable’, meaning that any future malware that exploits these could propagate from vulnerable computer to vulnerable computer without user interaction.  These vulnerabilities were discovered by Microsoft during hardening of Remote Desktop Services as part of our continual focus on strengthening the security of our products. At this time, we have no evidence that these vulnerabilities were known to any third party.
