Dear all,

Last month, the critical vulnerability regarding the secure connection (SSL) was discovered.
Especially, there is possibility of leaking the private information, a credit card, addresses, password and so on when you access a web browser to secure web sites, such as an online shopping, an online bank, or a local page with password.

Countermeasure of not only servers but also PCs are needed!!

Have my browser this vulnerability?
