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.</p> <p>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.</p> <p>The security update addresses the vulnerability by correcting how the Microsoft SMBv2/SMBv3 Client handles specially crafted requests.</p>
