[ale] OpenSSL Broken, Upgrade Now

[Lightner, Jeff]

Sorry but that’s wrong.   Port 22 is the default for ssh (and scp/sftp by etension) but some folks change the port.  While ssh etc… use openssl they are NOT the only tools that do so.  https does as well which is why there is discussion about SSL certificates.

If only your IPs could reach port 22, then you should be safe, unless one of your hosts was breached.

This article says that ssl certificates could have been stolen:

Does this really mean I need to replace the ssl keys on every one of my Amazon Linux boxes, even non-web servers with access allowed only from pre-assigned IP addresses? Please tell me it's not so!

TL;DR: Upgrade OpenSSL to >= 1.0.1g immediately, consider replacing keys.  Not as bad as Debian OpenSSL bug, but worse than "goto fail;".

"The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet. SSL/TLS provides communication security and privacy over the Internet for applications such as web, email, instant messaging (IM) and some virtual private networks (VPNs).

The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop communications, steal data directly from the services and users and to impersonate services and users."
