copied!<p>After reading most of the responses I think your question has been answered in an indirect way. I just wanted to point this out directly. Java doesn't suffer from the same problems you see in C/C++ because it protects the developer from these types of memory attacks (buffer overflow, heap overflow, etc). Those things can't happen. Because there is this fundamental protection in the language security vulnerabilities have moved up the stack.</p> <p>They're now occurring at a higher level. SQL injection, XSS, DOS, etc. You could figure out a way to get Java to remotely load malicious code, but to do that would mean you'd need to exploit some other vulnerability at the services layer to remotely push code into a directory then trigger Java to load through a classloader. Remote attacks are theoretically possible, but with Java it's more complicated to exploit. And often if you can exploit some other vulnerability then why not just go after and cut java out of the loop. World writable directories where java code is loaded from could be used against you. But at this point is it really Java that's the problem or your sys admin or the vendor of some other service that is exploitable?</p> <p>The only vulnerabilities that pose remote code potential I've seen in Java over the years have been from native code the VM loads. The libzip vulnerability, the gif file parsing, etc. And that's only been a handful of problems. Maybe one every 2-3 years. And again the vuln is native code loaded by the JVM not in Java code.</p> <p>As a language Java is very secure. Even these issues I discussed that can be theoretically attacked have hooks in the platform to prevent them. Signing code thwarts most of this. However, very few Java programs run with a Security Manager installed. Mainly because of performance, usability, but mainly because these vulns are very limited in scope at best. Remote code loading in Java hasn't risen to epidemic levels that buffer overflows did in the late 90s/2000s for C/C++.</p> <p>Java isn't bullet proof as a platform, but it's harder to exploit than the other fruit on the tree. And hackers are opportunistic and go for that low hanging fruit.</p>
