Unauthorized Access Attempt
Microsoft Internet Explorer is vulnerable to a heap-based buffer overflow in the Microsoft Windows implementation of the Vector Markup Language (VML). By creating a malicious HTML document containing specially-crafted VML records, a remote attacker could overflow a buffer and execute arbitrary code on the system with permissions of the victim, if the attacker could persuade the victim to open the malicious file. An attacker could exploit this vulnerability by hosting the file on a Web site or sending it to a victim as an email attachment.
Apply the appropriate patch for your system, as listed in the latest Microsoft Security Bulletin. See References.
