Subject:  [Full-disclosure] 0day: PDF pwns Windows

I am closing the season with the following HIGH Risk vulnerability:
Adobe Acrobat/Reader PDF documents can be used to compromise your
Windows box. Completely!!! Invisibly and unwillingly!!! All it takes
is to open a PDF document or stumble across a page which embeds one.

The issue is quite critical given the fact that PDF documents are in
the core of today's modern business. This and the fact that it may
take a while for Adobe to fix their closed source product, are the
reasons why I am not going to publish any POCs. You have to take my
word for it. The POCs will be released when an update is available.

Adobe's representatives can contact me from the usual place. My advise
for you is not to open any PDF files (locally or remotely). Other PDF
viewers might be vulnerable too. The issues was verified on Windows XP
SP2 with the latest Adobe Reader 8.1, although previous versions and
other setups are also affected.

A formal summary and conclusion of the GNUCITIZEN bug hunt to be expected soon.
