The host is installed with Windows 7 or Windows Server 2003 or Windows Server 2008 or Windows Vista or Windows XP and is prone to remote code execution vulnerability. A flaw is present in the OpenType Font (OTF) driver which fails to properly parse specially crafted OpenType fonts. Successful exploitation allows an attacker to run arbitrary code in kernel mode and hence install programs, view, change, or delete data or create new accounts with full user rights.
