Microsoft: Windows SMB Client Driver Information Disclosure Vulnerability


An information disclosure vulnerability exists in Windows when the Windows SMB Client kernel-mode driver fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could potentially disclose contents of System memory. To exploit this vulnerability, an attacker would have to log on to the system first and then run a specially crafted application in user mode. The security update addresses the vulnerability by correcting how the Windows SMB Client kernel-mode driver handles objects in memory.
