This vulnerability allows remote attackers to disclose sensitive information on affected 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 parsing of font files in the DirectWrite library. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before reading from memory. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process.
