There is a very, very small (but real) risk that while conducting business on that website, personal information could have been leaked from your computer to bad guys on the internet.
It's a small risk, but it's there and it's fixable. I'm dismayed that so many institutions have not immediately fixed this. All they have to do is upgrade their openssl software (extremely easy to do) and generate new private keys (not as simple, but very doable.)
At the moment the secure web is unbelievably fragile. I'm not sure when I'll log into my bank again.
