Description:	Summary: This host is missing a critical security update according to Microsoft KB4551762 Vulnerability Insight: The vulnerability is due to an error when the SMBv3 handles maliciously crafted compressed data packets. Both SMB Servers and clients are affected. To exploit the vulnerability against an SMB Server, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv3 Server. While as to exploit the vulnerability against an SMB Client, an unauthenticated attacker would need to configure a malicious SMBv3 Server and convince a user to connect to it. Vulnerability Impact: Successful exploitation will allow an attacker to execute code on the target SMB Server or SMB Client.
