Although it’s rapidly losing its relevance, Java still poses a security risk for any computer on which it’s installed. Java’s dangers are significantly lower now than in the past, because of all the major browsers, only Internet Explorer still runs Java code. All the others have stopped supporting Java completely.
Those of you still using Java, especially in Internet Explorer, should install Java 8 Update 151, because it includes fixes for twenty-two security vulnerabilities.
The easiest way to update Java is to visit the official Verify Java Version page, which will provide an update link if you’re running an out of date version.
