If you follow the thread between Jeff Walton and Kevin Wall, you will
see that #1 and #2 and close to being done.

I'm very much eager to hear what you and Kevin think is the best plan
of attack. I recommend you pull Jeff Walton (noloader at gmail.com) into
the conversation due to his very deep background in applied crypto.
Please CC me in as well, I am very familiar with the code in question.

In the meantime I will respect your wishes and give you and Kevin time
to figure out a plan of action.

If there is no action in this front, I'll do it myself - but I'd much rather see this come from the ESAPI project leaders.
>> Unfortunately, the reporting individual decided to disclose publicly instead of giving us the time to fix it first. If the disclosure was private, then I think Kevin and Chris should have been given the time to patch before the official bug report. The only reason I think we need to make a public official statement on this now is because the bad guys already have this information.
