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 or open a malicious file. In addition, the user must allow the web page to access the clipboard when so prompted. The vulnerability relates to how Internet Explorer converts bitmap-format graphics to PNG-format graphics. A web page can define an image using SVG, which, when copied and pasted back into the document, will overflow a heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process.
