Description: Some vulnerabilities have been reported in Internet Explorer, which can be exploited by malicious people to compromise a user's system.
1) An error exists in the Microsoft Multimedia Controls ActiveX control (daxctle.ocx) in the "CPathCtl::KeyFrame()" function. This can be exploited to cause a memory corruption by e.g. tricking a user into viewing a malicious HTML document that passes specially crafted arguments to the ActiveX control's "KeyFrame()" method.
Successful exploitation allows execution of arbitrary code.
NOTE: A somewhat working exploit is publicly available for partially patched versions of Windows 2000. However, Secunia has successfully created a fully working exploit for Windows XP SP2 (fully patched).
2) An error in Microsoft Multimedia Controls ActiveX control (daxctle.ocx) in the "Spline()" method may corrupt memory.
3) An error within the interpretation of HTML CSS "float" properties can be exploited via certain layout combinations to cause a memory corruption. This can be exploited to execute arbitrary code by tricking a user into viewing a specially crafted web page.
