Protection Provided by:	Security Gateway R81, R80, R77, R75, R71, R70
Who is Vulnerable?
Vulnerability Description	Office Text Converters are a default component of Microsoft Office that allow users to open and save files as older Office file formats. 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 6.0 file format. The vulnerability is due to a memory corruption error when WordPad and Office Text Converters parse a specially crafted file that includes malformed data. A remote attacker could trigger this flaw by convincing a victim to open a specially crafted document. Successful exploitation of this issue allows execution of arbitrary code once a malformed file is being loaded on a vulnerable system.
