Description: Multiple vulnerabilities have been reported in Internet Explorer, which can be exploited by malicious people to compromise a user's system. 1) An error within the instantiation of the chtskdic.dll COM object not intended to be instantiated in Internet Explorer can be exploited to corrupt memory. 2) An error in the "CTableCol::OnPropertyChange()" function when accessing properties of a table column in a named table row after calls to the "deleteCell()" JavaScript method can be exploited to corrupt memory via a specially crafted web page. 3) An error when calling property methods can be exploited to corrupt memory via a specially crafted web page. 4) Errors within the handling of HTML objects can be exploited to corrupt memory via a specially crafted web page. 5) An error in the handling of HTML objects can be exploited to corrupt memory via a specially crafted web page as a CMarkup object is used in certain cases after it has been freed. 6) An error in the media service component (msauth.dll) can be exploited to rewrite arbitrary files via a specially crafted web page. Successful exploitation of the vulnerabilities allows execution of arbitrary code. Solution: Apply patches.
