Heartbleed - When OpenSSL Breaks Your Heart

You've likely heard about the recent OpenSSL vulnerability, CVE-2014-0160, dubbed Heartbleed. The main takeaway of this vulnerability is that attackers can use this to obtain things like secret keys used for X.509 certificates, user names and passwords, instant messages, emails, and other highly sensitive information. For a technical analysis of the bug, check out this blog post. More information can be found here, as well.

This is not some theoretical vulnerability—this issue has been exploited, such as in this proof of concept code. Any versions of OpenSSL from versions 1.0.1 through 1.0.1f are affected.

Fortunately, this is not a design flaw, so other SSL implementations should not be affected, unless of course they made the same implementation error.

Because this attack does not trigger any loggable events, it would be best to err on the safe side and change your private keys and passwords, since they may have been leaked without any indication as such in any log files.

To protect yourself, we highly advise upgrading to OpenSSL 1.0.1g, which contains the fix. If you are using Retina, you can scan your systems to see if they are using a vulnerable version of the OpenSSL library with the following audits:

BeyondTrust products which utilize OpenSSL:
• Retina Network Security Scanner uses OpenSSL when performing SSL based remote auditing. It is recommended to upgrade to Retina 5.19.8 which includes OpenSSL 1.0.1g.
• PowerBroker Identity Services (including PBIS Open) uses OpenSSL, however it does not use the vulnerable SSL/TLS functionality from OpenSSL. Although the core functionality of the product is not affected, BeyondTrust is committed to updating the OpenSSL libraries as a priority.
• PowerBroker for Databases uses OpenSSL for communicating between agents. However, it is not using a version of OpenSSL that is susceptible to the Heartbleed bug.
• PowerBroker for Unix & Linux uses OpenSSL if SSL is enabled. However, it is not using a version of OpenSSL that is susceptible to the Heartbleed bug.
• PowerBroker Password Safe uses OpenSSL for portions of its two-factor token support. However, it is not using a version of OpenSSL that is susceptible to the Heartbleed bug.

** Retina Network Security Scanner 5.19.10 was released with an enhancement to audit 33686 (OpenSSL 1.0.1f and Prior TLS Read Overrun - Custom). The custom audit logic was updated to detect targets that do not support the SSL heartbeat request (and are thus not vulnerable to CVE-2014-0160). If heartbeat support is not detected, the target will not be audited for CVE-2014-0160. This addresses the issue outlined in HP KB c04249852 where iLO v1 and iLO v2 devices were DoSed by a heart bleed detection scan.
