Description: Secunia Research has discovered a vulnerability in Internet Explorer, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused due to an error in the file download queue handling when processing multiple concurrent attempts to start a file download. This can be exploited via a specially crafted web page to corrupt memory in a way that results in use of an already freed object. Successful exploitation allows execution of arbitrary code. Solution: Apply patches.
