Java 7 e 6 si aggiornano pensando alla sicurezza

Ieri Oracle, ha rilasciato due aggiornamenti per Java. Sono state aggiornate la versione numero 7, che raggiunge l’update numero 21, e la versione 6, che raggiunge l’update numero 45.

Entrabi gli aggiornamenti sono incentrati sulla sicurezza del linguaggio, in particolare in Java 7 è stata introdotta una Blacklist per i jar.

Ecco le novità della versione 7, J7u21:

• Blacklisted Jars and Certificates: Oracle now manages a certificate and jar blacklist repository. This data is updated on client computers daily on the first execution of a Java applet or web start application
• Changes to Java Control Panel's Security Settings: In this release, low and custom settings are removed from the Java Control Panel(JCP)'s Security Slider
• Changes to Security Dialogs: As of JDK 7u21, JavaScript code that calls code within a privileged applet is treated as mixed code and warning dialogs are raised if the signed JAR files are not tagged with the Trusted-Library attribute
• Changes to RMI: From this release, the RMI property java.rmi.server.useCodebaseOnly is set to true by default. In previous releases the default value was false
• Server JRE: A new Server JRE package, with tools commonly required for server deployments but without the Java plug-in, auto-update or installer found in the regular JRE package, is available starting from this release
• Fixes for security vulnerabilities

E della versione 6, J6u45:

• Changes to RMI: From this release, the RMI property java.rmi.server.useCodebaseOnly is set to true by default. In previous releases the default value was false.
• Fixes for security vulnerabilities
