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.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
