Microsoft » Powerpoint » 97 : Security Vulnerabilities, CVEs,

Vulnerability in (1) Microsoft Excel 2002 and earlier and (2) Microsoft PowerPoint 2002 and earlier allows attackers to bypass macro restrictions and execute arbitrary commands by modifying the data stream in the document.

Microsoft Office 2000 (Excel and PowerPoint) and PowerPoint 97 are marked as safe for scripting, which allows remote attackers to force Internet Explorer or some email clients to save files to arbitrary locations via the Visual Basic for Applications (VBA) SaveAs function, aka the "Office HTML Script" vulnerability.

PowerPoint 95 and 97 allows remote attackers to cause an application to be run automatically without prompting the user, possibly through the slide show, when the document is opened in browsers such as Internet Explorer.
