Symantec Security Response hasdiscovered an Adobe Acrobat PDF filecirculating the
internet which allows a hacker to take over a user's PC.
Symantec said, "This vulnerability is not one we have seen in
the wild before and affects Adobe Flash. The authors have taken a
bug and turned it into an exploit. Once the unsuspecting user
visits the website or opens the PDF, this exploit will allow
further malware to be dropped on the victim's machine and possibly
open a back door."
Symantec predicted that there will be more attacks that attempt
to exploit this vulnerability. Once the patch is available from
Adobe, users can update their systems. As an extra safety measure,
Vista users can employ the UAC (User Account Control) feature as
this will help mitigate a successful compromise, Symantec said.
