A remote user can create HTML with specially crafted XML that, when loaded by the target user via Internet Explorer, will trigger a flaw in the XML parser and execute arbitrary code on the target system [CVE-2007-0099]. The code will run with the privileges of the target user.

A remote user can create HTML that, when loaded by the target user via Internet Explorer, will trigger a flaw in the error checking of external document type definitions (DTDs) and access information from arbitrary domains on the target user's browser [CVE-2008-4029].

A remote user can create specially crafted HTML that, when loaded by the target user via Internet Explorer, will trigger a flaw in the processing of transfer-encoding headers and access information from arbitrary domains on the target user's browser [CVE-2008-4033].
