The threat is not new. Symantec regularly release activity reports and
from time to time a reporter looking for a story will pick one up and
do some work.
Any reputable antivirus/anti-malware/etc. application should pick up
at least some of these, but of course one must always be cautious
about the stray pdf you find in the street. Most pdf exploits are
pretty well documented.
Anyway, click on the link http://www4.symantec.com/Vrt/wl?tu_id=SUKX1271711282503126202
Go to pp 22-23, 42, 44, 45. It is all explained there.
user authorisation then you should be ok.
