Adobe Product Security Incident Response Team (PSIRT) Blog

In recognition of the important role that independent security researchers play in keeping Adobe customers safe, today Adobe launches a web application vulnerability disclosure program on the HackerOne platform. Bug hunters who identify a web application vulnerability in an Adobe online service or web property can now privately disclose the issue to Adobe while boosting their HackerOne reputation score. We invite security researchers to view the disclosure guidelines available here: https://hackerone.com/adobe.

Adobe continues to welcome the coordinated disclosure of security issues affecting desktop products and enterprise on-premise solutions by notifying our Product Security Incident Response Team (PSIRT@adobe.com).

Last week, industry security researchers announced a flaw in the OpenSSL encryption software library, known as “Heartbleed,” which can be used to cause a vulnerable system to reveal up to 64k of memory to an attacker.

Adobe has evaluated the Creative Cloud and its related services (including Behance and Digital Publishing Suite), the Marketing Cloud solutions and products (including Analytics, Analytics Premium and Experience Manager), EchoSign, Acrobat.com, the Adobe.com store, and other Adobe services. All Adobe internet-facing services known to have been using a version of OpenSSL containing the Heartbleed vulnerability have been mitigated. We are continuing our analysis of Adobe internet-facing servers to identify and remediate any remaining Heartbleed-related risks.

Some Adobe products and services do not bundle OpenSSL (such as ColdFusion** , Experience Manager and Experience Manager On-Demand) but are frequently deployed by customers on-premise or with third party web servers. We advise these customers to test for the Heartbleed vulnerability (CVE-2014-0160) against their deployment and configuration. If necessary, follow the recommendations provided by the OpenSSL security advisory as appropriate.

At this time, Adobe does not plan to initiate a password reset in response to the Heartbleed vulnerability; however it is always a good practice to change passwords from time to time. We strongly recommend that you change your Adobe password if you use the same user ID and password as your AdobeID and password on multiple websites, so that a compromise of your username and password on a non-Adobe service does not put your Adobe ID at risk.

** Update: ColdFusion does ship a version of OpenSSL that is not vulnerable to the Heartbleed vulnerability.

A prenotification Security Advisory has been posted in regards to upcoming Adobe Reader and Acrobat updates scheduled for Tuesday, May 14, 2013.

With the availability of Adobe Acrobat X solutions this week, a reminder to be cautious when receiving email messages purporting to offer a download of a new version of Adobe Acrobat or Adobe Reader sent by entities claiming to be Adobe.

Many of these emails require recipients to register and/or provide personal information. Please be aware that these emails have not been sent by Adobe or on Adobe’s behalf.

The Adobe Reader, in particular, is free software available for download directly from the Adobe Reader download page on the Adobe website at http://get.adobe.com/reader/; it is not available in any other manner via download, including via email.

Customers receiving one of these potentially malicious emails should delete the email immediately without clicking on any of the links.
