Foxit Reader has recently been affected by a series of security vulnerabilities which company managed to resolve shortly after they were disclosed.
The company behind the program has just released version 3.3 of Foxit Reader which introduces a new feature called Secure Trust Manager. It basically is a new component that blocks potentially malicious attacks before they can be executed or run.
An example would be the recent pdf exploit that made it possible to launch a file in Windows that was embedded in specially prepared pdf documents.
The Secure Trust Manager would prevent the execution and display a warning message instead.
Information are displayed to the user that outline why the execution has been blocked. The Trust Manager is activated by default in a standard installation of Foxit Reader. The setting can be disabled in the preferences by going to Tools > Preferences > Trust Manager.
Unchecking "Enable Safe Reading Mode" in the menu will disable the Trust Manager which is only recommended if the pdf that needs to be accessed is known to be secure.
Update: In newer versions of Foxit Reader, you need to perform the following operation: Select File > Preferences and Trust Manager in the preferences window that opens up. Here you find the option to enable Safe Reading more, or disable it if you do not want to use it. Instead of doing so, you can also only disable it for trusted documents.
There is unfortunately no option to disable the trust manager for the pdf that is currently viewed when the dialog opens up. The developers should also add a better description and more options to the feature. A pdf whitelist and blacklist would also come in handy.
The Secure Trust Manager adds to the security of the pdf reader Foxit Reader. The limited description on the developer's website leaves room for speculation as to which operations are protected by it.
The latest version of Foxit Reader can be downloaded directly from the developer's website.Advertisement
