This vulnerability was first described in Microsoft Security Advisory 980088.
An information disclosure vulnerability exists in the way that Internet Explorer handles content using specific strings when sanitizing HTML. (CVE-2010-1257)
A remote code execution vulnerability exists in the way that Internet Explorer accesses an object that has not been correctly initialized or has been deleted. (CVE-2010-1259, CVE-2010-1262)
A remote code execution vulnerability exists in the way that Internet Explorer accesses an object that has not been correctly initialized or has been deleted in the IE8 Developer Toolbar. (CVE-2010-1260, CVE-2010-1261)
Microsoft has released a security update that addresses these vulnerabilities by modifying the way that Internet Explorer handles objects in memory, HTML sanitization, and cached content. The security update is rated Critical for Internet Explorer 6 Service Pack 1 on Microsoft Windows 2000 Service Pack 4; Critical for Internet Explorer 6, Internet Explorer 7, and Internet Explorer 8 on Windows clients; and Moderate for Internet Explorer 6, Internet Explorer 7, and Internet Explorer 8 on Windows servers.
