From the press release:
Foxit, a leading provider of solutions for reading, editing, creating, organizing, securing PDF documents and eReader devices, announces the release of Foxit PDF Reader Version 3.3. The new Foxit Reader further enhances PDF document viewing security by implementing a Safe Mode feature.
In its continued efforts of providing safer, faster and more stable PDF software tools, Foxit addresses recent security concerns by releasing a new version of its popular Foxit Reader. This is a follow-up security improvement to the Foxit Reader release on April 2nd, 2010. Earlier this month, Foxit Reader adopted a warning message before running any executable command embedded in a PDF document. Version 3.3 adds a second level of security by giving the user an option for disabling all external commands. The new Trust Manager allows users to select a safe mode operation, once selected; no external commands will be executed by the Foxit Reader. The Trust Manager feature is easy-to-use and can be selected or deselected within the reader at the discretion of the reader.
