[ale] OpenSSL Broken, Upgrade Now

[Lightner, Jeff]

As a reminder this doesn’t affect web servers that were running openssl versions less than 1.0.1  (e.g. all RHEL5 and RHEL6.0 through RHEL6.4 were unaffected but RHEL6.5 and greater were).

The fact that RHEL5 used upstream 0.9.8x and backports bug and security fixes into that means it was unaffected because they never incorporated the upstream code into their extended version.

At least one of our partners did that the day the bug was announced.

Since you can’t tell whether you’ve been exploited or not some people are choosing to replace keys rather than worry about whether or not they’ve been exploited.

Symantec (Verigsing one of the CAs) sent an alert that if I read it properly suggests you should change your SSL certificate.

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."
