Microsoft: Windows SMB Information Disclosure Vulnerability
An information disclosure vulnerability exists in the way that the Microsoft Server Message Block 2.0 (SMBv2) server handles certain requests. An attacker who successfully exploited this vulnerability could craft a special packet, which could lead to information disclosure from the server. To exploit the vulnerability, in most situations, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv2 server. The security update addresses the vulnerability by correcting how SMBv2 handles these specially crafted requests.
