Foxit Corp has added new security features to its alternative PDF reader software to help thwart recent malware attacks that exploit the /launch feature. Foxit PDF Reader Version 3.3 has added a Safe Mode that blocks external commands from being executed by the software. The changes follow the discovery by researcher Didier Stevens that dangerous executables can be embedded into PDF files (and executed) without exploiting any vulnerabilities. Adobe has offered a workaround for the issue and is considering a better fix.
