The version of Microsoft’s Graphics Component installed on the remote host is affected by a heap overflow vulnerability. Specially crafted TrueType font files are not processed properly. A remote, unauthenticated attacker could exploit this vulnerability by getting a user to view content that contains malicious TrueType font files, resulting in arbitrary code execution.
Note that this issue is currently being exploited by malware in the wild.
