This vulnerability allows local attackers to escalate privileges on affected installations of Microsoft Windows. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the win32kfull.sys driver. The issue results from dereferencing a NULL pointer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM.

Microsoft Windows kernel contains an unspecified vulnerability that allows for privilege escalation.

Microsoft Active Directory Federation Services (AD FS) 2.0, 2.1, and 3.0, when a configured SAML Relying Party lacks a sign-out endpoint, does not properly process logoff actions, which makes it easier for remote attackers to obtain access by leveraging an unattended workstation, aka "Active Directory Federation Services Information Disclosure Vulnerability."
