Some of them have the maximum score on the CVSS 2.0 scale used by Oracle to rate the severity of vulnerabilities.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."The Java 7u21 release introduces changes to security messages related to running Java applets and applications," Oracle said in a technical document that explains the changes. "All Java applications executed via the user's browser will prompt the user for confirmation. The type of messages presented depends upon different risk factors such as running applications that include invalid digital certificates, and using out of date versions of Java."To read this article in full or to leave a comment, please click here
