Description
Two vulnerabilities have been reported in Microsoft Word, which can be exploited by malicious people to compromise a user's system.

1) An error when parsing objects in rich text format (.rtf) files can be exploited to cause a heap-based buffer overflow e.g. when a user opens a specially crafted .rtf file containing malformed strings with Word or previews a specially crafted e-mail containing malformed strings as rich text or HTML.

2) An error exists in the processing of cascading style sheets (CSS) values and can be exploited to corrupt memory when a specially crafted HTML file is opened using Word.

Successful exploitation may allow execution of arbitrary code.

Solution
Apply updates.
