CVE-2017-0273
The Microsoft Server Message Block 1.0 (SMBv1) allows denial of service when an attacker sends specially crafted requests to the server, aka "Windows SMB Denial of Service Vulnerability".
Does this matter?
Lower severity and a low EPSS score (6.09%). Track it; it rarely justifies an emergency change on its own.
