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 NtUserfnINOUTNCCALCSIZE function. The issue lies in the failure to sanitize a buffer before calling a userland function resulting in the leak of an address on the kernel trap frame. An attacker can leverage this in concert with another vulnerability to achieve code execution at SYSTEM.
