Multiple vulnerabilities have been identified in Microsoft Internet Explorer, which could be exploited by remote attackers to take complete control of an affected system.
The first issue is caused by a memory corruption error when instantiating the "chtskdic.dll" COM object as an ActiveX control, which could be exploited by remote attackers to execute arbitrary code by tricking a user into visiting a specially crafted web page.
The second vulnerability is caused by a memory corruption error when accessing a previously deleted object, which could be exploited by malicious web sites to compromise a vulnerable system.
The third issue is caused by a memory corruption error when calling the property method, which could be exploited by remote attackers to execute arbitrary code by tricking a user into visiting a specially crafted web page.
The fourth vulnerability is caused by memory corruption errors when accessing uninitialized memory, which could be exploited by malicious web sites to compromise a vulnerable system.
The fifth issue is caused by an arbitrary file rewrite error in the "mdsauth.dll" control of Microsoft Windows Media Server, which could be exploited by remote attackers to execute arbitrary code by tricking a user into visiting a specially crafted web page.
