WEP is unsecure and whoever still uses WEP can just turn off the WLAN security. There is no difference. It doesn't take longer than 10 minutes to crack the WEP key. WPA is secure. But unfortunatly the security is as powerfull as the WLAN password ist. There exist tools which try to crack the password with brute force attacks.

Heartbleed is a coding bug in the OpenSSL component, which allows to get the OpenSSL heartbeat to expose sensitive data. There are a lot of reasons to use OpenSource but unfortunately this issue also uncovers a major drawback.
