Remote code execution vulnerabilities exist in the way that the Microsoft Server Message Block 1.0 (SMBv1) server handles certain requests. An attacker who successfully exploited the vulnerabilities could gain the ability to execute code on the target server.To exploit the vulnerability, in most situations, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv1 server.The security update addresses the vulnerabilities by correcting how SMBv1 handles these specially crafted requests.
This has been exploited as part of the WannaCry (a.k.a. WannaCrypt, WannaCryptor, Wcry) Ransomware Attacks.
