Microsoft Windows Kernel Type 1 Font Processing Out-Of-Bounds Read Information Disclosure Vulnerability

This vulnerability allows attackers to disclose sensitive information on affected 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 handling of Type 1 fonts in the Windows kernel. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute code in the context of the kernel.
