Foxit, a popular alternate choice to Adobe Reader for PDF files, and the program frequently suggested as a more “secure alternative”. No patch has been released yet.
Andrea Micalizzi an Italian security researcher, recently disclosed a flaw he discovered in the Foxit PDF plug-in for Mozilla Firefox. The vulnerability would admit an attacker to write to any memory location. The vulnerability isn’t found within Foxit’s software, but the DLL file that creates the link between Foxit and Firefox.
Also, this issue has only been confirmed with Mozilla’s browser, while Foxit is available on several platforms, the others may very well be safe. Also, a working proof of concept has not been released.
