Critical Oracle Java Security Update


Oracle released the scheduled critical security updates for its Java SE Runtime Environment software.

This is a Critical Patch Update that contains 51 new security fixes for Oracle Java SE.  Oracle indicated that fifty (50) of the Java SE vulnerabilities fixed in this Critical patch Update are remotely exploitable without authentication.

Additional details about the update are available in the Oracle Quality Assurance Blog post, referenced below.  If Java is still installed on your computer, it is recommended that this update be applied as soon as possible due to the threat posed by a successful attack.

For those people who have desktop applications that require Java and cannot uninstall it, Java can now be disabled in Internet Explorer.  See Microsoft Fix it to Disable Java in Internet Explorer.

Java Security Recommendations

1)  In the Java Control Panel, at minimum, set the security to high.
2)  Keep Java disabled until needed.  Uncheck the box "Enable Java content in the browser" in the Java Control Panel.

3)  If you use Firefox, install NoScript and only allow Java on those sites where it is required.

Instructions on removing older (and less secure) versions of Java can be found at
