Windows Denial of Service Vulnerability
A denial of service vulnerability exists in implementations of the Microsoft Server Message Block 2.0 and 3.0 (SMBv2/SMBv3) client. The vulnerability is due to improper handling of certain requests sent by a malicious SMB server to the client. An attacker who successfully exploited this vulnerability could cause the affected system to stop responding until it is manually restarted.
To exploit the vulnerability, an attacker could use various methods such as redirectors, injected HTML header links, etc., which could cause the SMB client to connect to a malicious SMB server.
The security update addresses the vulnerability by correcting how the Microsoft SMBv2/SMBv3 Client handles specially crafted requests.

Microsoft Windows 10 Gold, 1511, and 1607; Windows 8.1; Windows RT 8.1; Windows Server 2012 R2, and Windows Server 2016 do not properly handle certain requests in SMBv2 and SMBv3 packets, which allows remote attackers to execute arbitrary code via a crafted SMBv2 or SMBv3 packet to the Server service, aka "SMBv2/SMBv3 Null Dereference Denial of Service Vulnerability."
