Three recent vulnerabilities in Java have paved the way for malware exploitation and all three have had patches available for some time. The vulnerabilities are multi-platform (Linux, Mac, Windows) and can allow remote code execution. The MMPC has a table with a few details about the vulnerabilities, what is notable is that two of the vulnerabilities went from hundreds of thousands of attacks per quarter to millions. Another reason that Java attacks are becoming ubiquitous is that they are highly successful and extremely productive. Krebs says that.
