Oracle has released Java 7 Update 13. In an announcement, Oracle explains that the update was originally slated to go live February 19th, but that it was pushed out early because of “active exploitation in the wild of one of the vulnerabilities affecting the Java Runtime Environment (JRE) in desktop browsers.” In all the code fixes 50 security holes; 44 of these are said to have been browser-only.
Apple recently blocked Java in OS X for a second time following concerns that Update 11 still had serious gaps. That may have caused problems for some Mac users however, since it broke any websites or apps based on the software. With the launch of Update 13, Java has resumed working in OS X.
