Microsoft Windows could allow a remote or local attacker to execute arbitrary code. When instantiating the Microsoft DDS Library Shape Control (Msdds.dll) object, or other COM objects, as ActiveX controls, a memory corruption error can occur. A remote attacker could exploit this vulnerability by creating a malicious Web page and hosting it on a Web site or by sending it to a victim as an HTML email. The attacker could execute arbitrary code on the system and take complete control over the victim's system or cause Internet Explorer to crash when the victim opens the Web page.
