Who is Vulnerable?
Vulnerability Description WordPad Text Converters allow users who do not have Microsoft Office Word installed to open documents in other Microsoft Windows applications. A remote code execution vulnerability has been reported in Microsoft WordPad. The vulnerability is due to an error in the WordPad converter that fails to correctly parse the sprmTTextFlow and the sprmTSplit fields in a Word document.
