Oracle will release a new version of Java on Tuesday that will include 42 security fixes and will make changes to how Web-based Java content will be presented inside browsers. Thirty-nine of the vulnerabilities patched by the new Java 7 Update 21 (7u21) can be exploited remotely without authentication, Oracle said in a pre-release announcement. In addition to security fixes, the new update will also make changes to how Java applets — Web-based Java applications — are handled and presented in Web browsers that have the Java plug-in enabled.
