We recommend that until your system is updated, do not open PDF documents received unexpectedly or without a confirmed source by email, do not open links to PDF documents on websites, and consider disabling the JavaScript interface in Acrobat Reader and enabling Data Execution Protection on Windows systems.

These three recommendations all come with a cost. Adobe PDF documents and the software for viewing them have become part of most businesses workflow. If your business application created the PDF within your network as part of a reporting process - then the file should be considered safe. If someone emails you a PDF or a link to a website with information in a PDF - you should be extremely cautious at this point. Once Adobe releases the updates, you should get your Acrobat products patched immediately.

Please use safe web browsing and email practices. Your servers should never be used for web-browsing except for updates from trusted web sites (such as Microsoft). Your users should be logged into their desktop or remote sessions as non-administrator level users. Systems administrators should have separate administrator-level accounts to help limit risks during their daily activities.
