Highly critical flaw found in IE

Secunia said in an alert that the vulnerability is due to an error in the processing of the "createTextRange()" method call applied on a radio button control.

"This can be exploited by a malicious Web site to corrupt memory in a way that allows the program flow to be redirected to the heap," Secunia said in the alert, warning that successful exploitation allows execution of arbitrary code whenever the target visits the rigged Web site.
