The responsible way to handle a security vulnerability...

The responsible way to handle a security vulnerability report is to let the vendor know you believe you've found a potential vulnerability in their product so they can investigate it. That wasn't done in this case, and it's really unfortunate because the result has been that customers have been unnecessarily frightened about this issue because we were given a grand total of fewer than 12 hours between the initial report of the vulnerability and the time it went public. The goal at the end of the day is to protect customers, and responsible reporting practices suggest that the right way is to give the vendor a chance to do the investigation.
