F-Secure released an article about security advisories on Microsoft products including Word Viewer and Access Snapshot Viewer.

It notes that there is a bug in Word 2002 with Service Pack 3 and they advise their readers to download Word Viewer 2003 as a workaround.

For the Access Snapshot Viewer issue, it is a vulnerability in the ActiveX Control which could allow remote code execution. One of the cases that they studied is a patent themed site. They note that it was hacked and the ActiveX exploit was also taken advantage of.

The Snapshot tool ships with many versions of Access prior to the latest version which is 2007.
