More Information

More information about this security update

Known issues with this security update

This security update adds a new version of the DHTML Editing Control that injects the following META elements into the document containing the DHTML Editing Control for each operation that targets the document's HTML.
<META content="text/html; charset=unicode" http-eqiv=Content-Type>
<META name=GENERATOR content="MSHTML <version>">
The SourceCodePreservation property is obsolete in the DHTML Editing Control. This may break the existing applications that are incompatible with the additional encoding of the character set to Unicode. One method to resolve this issue is to identify the META element in the output stream and to replace the character set specification with the desired encoding.

As part of the attack surface reduction effort, code that provided partial preservation of markup formatting was removed from the DHTML control. The new DHTML control sends data directly to MSHTML and returns HTML output. MSHTML and the DHTML control do not fully preserve formatting. MSHTML provides visual rendering of "normalized" HTML by adding missing elements. These normalization changes include adding the closing </td> tag, adding the <html> and <head> tags, and positioning the <style> tag and the <script> tag elements inside the <head> element. The DHTML control parses the HTML into a document model and then re-creates it from the model when you save the file. Additional formatting can be achieved by using the HTML Tidy tool on the output from the DHTML control. For more information about the HTML Tidy tool, visit the following Web site:
