Description:
Some vulnerabilities have been reported in Internet Explorer, which can be exploited by malicious people to compromise a user's system.

1) A use-after-free error in mshtml.dll when handling "setExpression()" method calls can be exploited to dereference previously freed memory via a malicious web page containing specially crafted script code.

2) An error within the handling of the "cloneNode()" and "nodeValue()" methods can be exploited to corrupt memory via a malicious web page containing specially crafted script code.

3) An error when handling document objects that have been created, modified, deleted, and are then accessed can be exploited to corrupt memory via a malicious web page containing specially crafted script code.

4) An error when displaying web pages containing certain unexpected method calls to HTML objects can be exploited to corrupt memory.

NOTE: This vulnerability is reportedly being actively exploited.

Successful exploitation of the vulnerabilities allows execution of arbitrary code when a user e.g. visits a malicious website.
