Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-09-038 
June 10, 2009

-- CVE ID:
CVE-2009-1530

-- Affected Vendors:
Microsoft

-- Affected Products:
Microsoft Internet Explorer

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Microsoft Internet Explorer. User
interaction is required to exploit this vulnerability in that the target
must visit a malicious page.

The specific flaw exists when repeatedly calling event handlers after
adding nodes of an HTML document. When a specially crafted webpage is
repeatedly rendered, memory is improperly reused after it has been
freed. Due to the controllable nature of the web browser, this
vulnerability can be exploited to remotely compromise a system running
under the security context of the currently logged in user.

-- Vendor Response:
Microsoft has issued an update to correct this vulnerability. More
