[ale] OpenSSL Broken, Upgrade Now

Thu Apr 17 14:38:01 EDT 2014

By the way CLIENTS as well as SERVERS are affected.   That means if you have openssl on a server where you run “curl” or “wget” or other outbound utilities they are vulnerable.

From the curl site:
“Heartbleed is a flaw in OpenSSL in a certain version span. Clients are *also*
vulnerable to this flaw, which means that if you run curl or libcurl with a
vulnerable OpenSSL version a rogue server can read client memory.”

I think it is a bad idea to NOT do the update if you have the vulnerable version of openssl installed.   Assuming you’re ok because you’re only using ssh will be a bad idea.   You may someday start https for some reason (or may even already have it running with say RedHat or Apache’s default page).   Also openssl might be included in 3rd party tools you’re using or even in a specialized pam module.

Of course it does make sense to prioritize – SSL web servers on the internet first, then any other internet facing systems, then internal systems.

So is OpenSSH _using_ OpenSSL for encryption processes?

Yes, but OpenSSH is not vulnerable to Heartbleed.

OpenSSH uses OpenSSL for cryptographic primatives, but OpenSSH does not use TLS.  Heartbleed is a vulnerability in the TLS implementation within OpenSSL; specifically, an error in processing incoming TLS messages.  Since OpenSSH doesn't use TLS, it doesn't process TLS messages, so there's no risk from Heartbleed.

Thanks! So ssh uses it's own heartbeat function and not the one in OpenSSL which has the massive leak.

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."

Every time you stop a school, you will have to build a jail. What you gain at one end you lose at the other. It's like feeding a dog on his own tail. It won't fatten the dog.
