Microsoft Windows Font Integer Overflow Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on vulnerable 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 rendering of fonts. A crafted OpenType font rendered by the kernel can trigger an integer overflow before writing to memory. An attacker can leverage this vulnerability to escalate privileges and execute code as SYSTEM.
