I’ve seen stories online suggesting that, since there’s no patch yet, you might consider switching to a different PDF reader.īut since the bug isn’t in the reader itself (and there’s no exploit yet, anyway), there’s a quicker and simpler mitigation you can use that will let you stick with Foxit. Below, for example, the query part is the string download=true:įoxit has yet to comment on this issue on its security advisories, though I am sure it will soon do so. The query component is usually used to identify parameters submitted to a server-side script. If a link contains a question mark, the query is the text that follows it. The buffer overflow happens in the code that processes the link, triggering a crash when the link includes an overly-long query string. You just have to feed it a malformed link that, when clicked, serves up an HTTP reply that advertises itself as a PDF. Intriguingly, you don’t actually need to feed Foxit a PDF to provoke the crash. Ironically, the first example of such a plugin for Netscape was written at…Adobe Systems.

That’s not good.įoxit openly promotes its PDF reader as a secure platform that “ insures worry free operation against malicious virus ”, which may sound like a bold statement in the face of Micalizzi’s bug.īut there is still literal truth in Foxit’s claim: the bug is not in the PDF reader itself, but in the npFoxitReaderPlugin.dll file that acts as the glue between the browser and the reader. The crash, which is a side-effect of a stack overflow, pretty much lets you write to a memory location of your choice. (I used Firefox 18.0 with Foxit Plugin 2.2.1.530 on Windows XP3.) Micalizzi hasn’t actually produced a proof-of-concept exploit, but I was able to reproduce his result at will. Here’s an example: Italian security researcher Andrea Micalizzi has recently sought, and found, a possibly-exploitable vulnerability in the latest Foxit PDF plugin for Firefox.

You can therefore expect other vendors of PDF software to start feeling some of the heat that would probably have been aimed entirely at Adobe in years gone by.

Foxit PDF Reader allows you to create PDF from common file formats. That’s because Adobe’s PDF reader has long been the most prevalent product in the marketplace, and the most heavily targeted by attackers and researchers.īut there are plenty of challengers in the PDF software market, and it’s important to remember that just “being different” is not enough to deliver security on its own.Īlso, since Adobe released Reader X, with its security-oriented sandbox, crooks and researchers alike have found Adobe’s PDF nut much harder to crack. The connected world shares documents in the PDF format.
