We are just living through the worst online security catastrophe in long time and we will feel the impact of this problem for months to come. OpenSSL library which is used by many websites has a fault. This library is not only used on websites, it is also used by many vendors who provide security products to secure communications. In short, there is a good chance your network security vendor is also using this library in the products you trust to secure your network. For example, on email, TLS, which is used to tunnel emails between two gateways, may be vulnerable. Although the attacker may have to be a bit more sophisticated than a standard web attack, a door is open.
