Much has been made of the industry-wide Heartbleed vulnerability and its potential exploitation. Cisco was among the first companies to release a customer Security Advisory when the vulnerability became public, and is now one of many offering mitigation advice.
Those dealing with this issue on a day-to-day basis know it’s not enough to just patch the OpenSSL software library. Organizations also need to revoke and reissue digital certificates for their Heartbleed-vulnerable sites. If your certificates were stored in a Trust Anchor Module (TAM), they are still safe. Otherwise, a few additional steps should be taken to ensure you and your customers are secure:

The recent OpenSSL Heartbleed vulnerability has shown that technology leaders must work together to secure the Internet’s critical infrastructure. That’s why Cisco is proud to be a founding supporter of the Linux Foundation initiative announced yesterday (April 24th).
The initiative will fund open source projects that are critical to core computing and Internet functions, and Cisco sees security technologies as a fundamental infrastructure component. The first project being considered for funding is OpenSSL. As a longtime contributor to open source and user, we’ve offered code and intellectual property to enhance OpenSSL. We’ve also provided patches and testing results to help address vulnerabilities. Today’s announcement takes that commitment a step further.
We are pleased to help form a critical mass of governance, funding, and focus that will support the output of open source communities like OpenSSL. By working together as an industry, we can expect greater security, stability, and robustness for components that are critical to the Internet.

By now, almost everyone has heard of the OpenSSL Heartbleed vulnerability with CVE id CVE-2014-0160. The vulnerability has to do with the implementation of the TLS heartbeat extension (RFC6520) and could allow secret key or private information leakage in TLS encrypted communications. For more detailed information, visit the VRT’s analysis.

Today, we released the first Cisco IOS Software Security Advisory Bundled Publication of 2014. Six years ago, Cisco committed to disclosing IOS vulnerabilities on a predictable schedule (on the fourth Wednesday of March and September each calendar year) in direct response to your feedback. We know this timeline allows your organization to plan ahead and ensure resources are available to analyze, test, and remediate vulnerabilities in your environments.
Today’s edition of the Cisco IOS Software Security Advisory Bundled Publication includes six advisories that affect the following technologies:
- Session Initiation Protocol
- Network Address Translation
- Internet Key Exchange Version 2
- SSL VPN
- Cisco 7600 RSP720 with 10GE Uplinks
