Vulnerability Description	WordPad Text Converters allow users who do not have Microsoft Office Word installed to open documents in other Microsoft Windows applications. They also allow users to save documents in the Word 97 file format. The vulnerability is due to a memory corruption error when a user opens a specially crafted Word file in an affected version of Microsoft WordPad. A remote attacker could trigger this flaw by convincing a victim to open a specially crafted document.
