According to reports yesterday and today, a new zero-day vulnerability has been discovered in Adobe’s Reader and Acrobat (version 11.0.1) PDF reading and creation products. Fireeye, a security company, also reported that this vulnerability is being exploited in the wild already, so caution your users to be even more careful than usual when it comes to opening PDF files. There’s not a lot of information available yet about the exploit, but Adobe’s own blog says their security team is currently investigating.
