## Technical details

A heap-based buffer overflow exists in Microsoft Standard XPS, a Windows component responsible for parsing and processing XPS (XML Paper Specification) files. The vulnerability is triggered during the parsing of specially crafted XPS files and requires an attacker to be already authenticated with local access to the system. Successful exploitation allows privilege escalation from the current user context to a higher privilege level (such as SYSTEM). The attack is local in nature and does not require network access or user interaction beyond file handling. A patch is expected from Microsoft's security updates.
