New Java version: 8 Update 131

Earlier this week Oracle posted its quarterly Critical Patch Advisory for April 2017. Most of the Oracle software affected by these updates is likely only of interest to system administrators and developers, but buried in the advisory is a list of eight security vulnerabilities in Java 8 Update 121. Although it’s not mentioned in the advisory, those Java vulnerabilities are addressed in a new version of Java: 8 Update 131.

Anyone who uses a web browser with a Java plugin enabled should install Java 8 Update 131 as soon as possible. These days, Firefox, Chrome, and other Chrome-similar browsers like Vivaldi don’t support Java at all, so that leaves Internet Explorer. You can check whether Java is enabled in Internet Explorer by pointing IE to the official Java version test page.

Even if you don’t use a browser with Java enabled, you may have a version of Java installed on your computer, in which case you should consider updating it. You can find out whether Java is installed by looking for the Java applet in the Windows Control Panel. If it’s there, Java is installed; go to the Update tab and click Update now to install the new version.

Oracle sued by the FTC

If you visit the main Java page, you may notice a large all-caps message at the very top of the page: IMPORTANT INFORMATION REGARDING THE SECURITY OF JAVA SE. The message links to a page that discusses an ongoing lawsuit:

The Federal Trade Commission, the nation’s consumer protection agency, has sued us for making allegedly deceptive security claims about Java SE. To settle the lawsuit, we agreed to contact you with instructions on how to protect the personal information on your computer by deleting older versions of Java SE from your computer.

This is a good reminder that Java installers tend to leave old versions and related junk on Windows computers, and that you should always check for and remove old versions of Java after you install a new version. Visit the Java uninstall page and the Java uninstall help page to get started.
