Microsoft Internet Explorer CDispNode Use-After-Free Remote Code Execution Vulnerability

CVE ID	CVE-2013-0023
CVSS SCORE	6.8, AV:N/AC:M/Au:N/C:P/I:P/A:P
AFFECTED VENDORS	Microsoft
AFFECTED PRODUCTS	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 or open a malicious file. The specific issue is due to the way Internet Explorer handles SVG objects. A use-after-free condition can be created when an SVG references a self-referent SVG. By abusing this behavior an attacker can ensure this memory is under control and leverage the situation to achieve remote code execution under the context of the user running the browser.
ADDITIONAL DETAILS	Microsoft has issued an update to correct this vulnerability. More details can be found at: http://technet.microsoft.com/en-us/security/bulletin/MS13-009
