Microsoft Windows NtUserGetComboBoxInfo Stack Information Disclosure Vulnerability

This vulnerability allows local attackers to leak sensitive information on vulnerable installations of Microsoft Windows. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of the NtUserGetComboBoxInfo function. The issue lies in the failure to sanitize a buffer before returning its contents resulting in the leak of a kernel address. An attacker can leverage this together with another vulnerability to achieve code execution at SYSTEM.
