Though recent versions of OS X no longer ship with a Java plug-in -- and Apple has ceased developing its own versions and left compatibility to Java owner Oracle -- the company is pushing an updated version of Oracle's latest release of Java SE 6 (version number 1.6.0 build 37) through its own Software Update mechanism. The update fixes a critical "zero-day" exploit reported at the end of last month and is available as separate releases for OS X 10.6, and OS X 10.7 and higher.
