## Technical details

A heap-based buffer overflow exists in Microsoft Standard XPS, triggered during processing of malformed XPS documents. The vulnerability requires local access and authentication to the affected system. An attacker with these preconditions can craft a specially formatted XPS file that, when processed, causes a buffer overflow on the heap, enabling arbitrary code execution with elevated privileges. Microsoft has released patches addressing this vulnerability.
