Adobe is aware of reports that these vulnerabilities are being exploited in the wild in targeted attacks designed to trick Windows users into clicking on a malicious PDF file delivered in an email message.
I would hope people on this forum aren't dumb enough to try to open stuff in rogue emails. If it's not from someone you know, don't open it. If it is from someone you know, make sure they truly sent it.
No need to start panicking and altering your Adobe settings...
