This can be exploited to cause a buffer overflow by tricking a user to visit a malicious web site or view a malicious email. Successful exploitation allows execution of arbitrary code with the privileges of the user running Internet Explorer or another program using the Internet Explorer rendering engine. 2) The vulnerability is caused due to an error in the verification of redirects from XML resources. This can be exploited by tricking a user into visiting a malicious web site. Successful exploitation allows exposure of information from remote resources and local files. Other potentially security related issues have also been addressed by this bulletin. SOLUTION: Apply patches.
