A critical vulnerability has been identified in Adobe's Acrobat and Reader
software which affects Internet Explorer users.

As well as causing crashes, the frailty could allow a botnet to take
control of the whole computer when a PDF is opened within Explorer.


The hole is present in Acrobat Standard and Professional versions 7.0.0 to
7.0.8, and Adobe Reader 7.0.0 to 7.0.8. Only Microsoft's browser is
vulnerable.

Adobe's programmers are working on a patch, which should be available on
its support site soon. In the meantime, deleting AcroPDF.dll from the will
prevent Explorer from opening PDFs in the browser window.

Adobe's advisory is here.(JB:  embedded link:
