Adobe Reader and Acrobat security initiative

Brad Arkin, the Director of Product Security and Privacy at Adobe has outlined their efforts in making sure Adobe comes out with more secure products in the future:

1. Code Hardening – For the past several years all new code and features for Adobe Reader and Acrobat have been subject to our modern Secure Product Lifecycle (SPLC). The Adobe SPLC is similar to Microsoft’s Security Development Lifecycle (SDL). The Adobe SPLC integrates standard secure software activities such as threat modeling, automated and manual security code reviews, and fuzzing into the standard Adobe Product Lifecycle we follow for all projects.

The SPLC activities have been successful in mitigating threats in new code development, but did not fully address problems in the existing code base. Therefore, an initiative in the current security effort has been focused on hardening at-risk areas of the legacy code. We’ve applied the latest SPLC techniques against these prioritized sections of each application. Even in cases where no immediate vulnerability was identified, we have been strengthening input validation on a best-practice basis. (Experience shows such validation is a powerful tool in preventing as-yet unidentified security holes.)

2. Incident Response Process Improvements – We’ve targeted several specific areas where we are improving our incident response process. We expect folks outside Adobe will see more timely communications regarding incidents, quicker turn-around times on patch releases, and simultaneous patches for more affected versions as we move forward.

This approach was tested sooner than we would have liked with CVE-2009-1492/1493. Although this incident fell in the middle of our security effort, we were encouraged by the progress our response demonstrated. We worked to communicate early and often via our PSIRT blog and two weeks later, on May 12, 2009, we simultaneously shipped 29 binaries to update 17 different versions of Adobe Reader and Acrobat covering 32 languages for the Windows, Mac, and UNIX platforms.

3. Regular Security Updates – Starting this summer with the initial output of our security code hardening effort, we plan to release security updates for all major supported versions and platforms of Adobe Reader and Acrobat on a quarterly basis. Based on feedback from our customers, who have processes and resources geared toward Microsoft’s “Patch Tuesday” security updates, we will make Adobe’s quarterly patches available on the same days. (Although our 3/10/09 and 5/12/09 security patches landed on Patch Tuesday, the timing was coincidental. In both cases, we shipped the patches as soon as we finished testing them.)
