An exploit (it seems to be a very critical one) endanger our informations transmitted on Internet. If you have servers and you administer them, you have risks to be vulnerable with SSL/TLS service.

To explain brievely, a buffer overflow attack (send data in specifical size and format) can give access to data that have been transmitted encrypted to the server.

You can fix it in a simple way, an apt-get update && apt-get upgrade or yum update should do it. Restart services using this library or reboot your server in a doubt with reboot command.

Finally test your server at this address to check you have fixed it.
