May 2020: Microsoft Windows Transport Layer Security Denial of Service Vulnerability
CVE-2020-1118 Published on May 21, 2020

Microsoft Windows Transport Layer Security Denial of Service Vulnerability
A denial of service vulnerability exists in the Windows implementation of Transport Layer Security (TLS) when it improperly handles certain key exchanges. An attacker who successfully exploited the vulnerability could cause a target system to stop responding. To exploit this vulnerability, a remote unauthenticated attacker could send a specially crafted request to a target system utilizing TLS 1.2 or lower, triggering the system to automatically reboot. The update addresses the vulnerability by changing the way TLS key exchange messages are validated.
