Support Note: Secunia Advisory SA43776

On March 15, 2011 a Secunia security advisory was issued ( with regards to the Foxit® Reader. The vulnerability is due to an insecure “createDataObject()” function in the JavaScript API. This insecure function allows the creation of arbitrary files with controlled content via a specially crafted PDF file. This function could be taken advantage of maliciously and compromise the security of your computer.

To protect against harm, Foxit Reader users need to update their Reader to the latest version and then enable Safe Reading Mode. The most up-to-date Foxit Reader can be installed by choosing the Help->Check for Updates Now. When the pop-up box appears, click on the Preferences box on the bottom and then enable the automatically check for Foxit updates function. Enabling Safe Reading Mode can be accomplished by choosing Tools->Preference->Trust Manager and then by clicking the option of Enable Safe Reading Mode. This can also be done during initial installation of the Foxit Reader. Safe Reading Mode enables users to control unauthorized actions and data transmissions; including URL connections, launching external files, and running JavaScript functions, to efficiently avoid attacks from malicious documents. If Safe Reading Mode is disabled, users must only open trusted PDF documents to guard against malicious attacks.

If you have any questions regarding this advisory, or any other questions, please contact Foxit by phone (+1-866-MYFOXIT or +1-866-693-6948) or email us at
