Windows Crypto Driver Information Disclosure Vulnerability - CVE-2016-7219

An information disclosure vulnerability exists when a Windows Crypto driver running in kernel mode improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.

To exploit the vulnerability, an attacker would have to log on to an affected system and run a specially crafted application.

The update addresses the vulnerability by correcting how the Windows driver handles objects in memory.

The following table contains a link to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:

Windows Installer Elevation of Privilege Vulnerability - CVE-2016-7292

An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. To exploit the vulnerability, a locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation.
