Description:
Two weaknesses have been reported in Adobe Reader and Adobe Acrobat, which can be exploited by malicious people to enumerate files on a user's system or crash the application.

1) An error in the "LoadFile()" method makes it possible to determine if a queried local file exists via e.g. a malicious web site invoking the Internet Explorer ActiveX control directly.

2) An error within the processing of certain PDF documents can be exploited to crash the application via a PDF document containing a negative root page node "Count" value.

The weaknesses have been reported in versions 7.0 and prior for Windows.
