<< No. It depends on who discovered the flaw and if they reported it to the PHP guys.
I guess so. Who would be most at risk? The banks? Ecommerce? Or everyone? >>
I cant think of many BIG sites that use PHP, but anyone that uses PHP on linux/Solaris seems to be affected. That would be *MOST* of the PHP sites out there (Im sure most PHP sites run on Linux). And anyone that purchases things off these sites would be at risk I guess.
The reason I mentioned it is because plenty of people here like PHP and they may not keep up with security updates. I wasnt sure which forum to post it in, but OS seemed the most visited between OS, Networking, and Software... Off Topic would be fine, but not everyone goes there either.
