Microsoft splwow64 Information Disclosure Vulnerability

An information disclosure vulnerability exists in how splwow64.exe handles certain calls. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system (low-integrity to medium-integrity). This vulnerability by itself does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability (such as a remote code execution vulnerability or another elevation of privilege vulnerability) that is capable of leveraging the elevated privileges when code execution is attempted. The security update addresses the vulnerability by ensuring splwow64.exe properly handles these calls.

Active Directory Information Disclosure Vulnerability

An information disclosure vulnerability exists when Active Directory integrated DNS (ADIDNS) mishandles objects in memory. An authenticated attacker who successfully exploited this vulnerability would be able to read sensitive information about the target system. To exploit this condition, an authenticated attacker would need to send a specially crafted request to the AD|DNS service. Note that the information disclosure vulnerability by itself would not be sufficient for an attacker to compromise a system. However, an attacker could combine this vulnerability with additional vulnerabilities to further exploit the system. The update addresses the vulnerability by correcting how Active Directory integrated DNS (ADIDNS) handles objects in memory.
