Bug: Acrobat & Reader 7.0 and earlier
Source: Blogcritics.org
Adobe Acrobat 7.0 and earlier, and the Adobe Reader 7.0 and earlier have a bug in the way they interact with an Internet Explorer ActiveX control. If this control is invoked directly by a webpage, an attacker may be able to learn whether certain local files exist. This will only happen on a computer that is running Microsoft Internet Explorer. According to Adobe, the file contents are not exposed. This has been fixed in the Adobe Acrobat and Acrobat Reader 7.0.1 update.
