Is Java 1.5 safe?

There was recently a security alert from Sun about J2SE 5.0 and 1.4.2 (see http://sunsolve.sun.com/search/document.do?assetkey=1-26-101749-1 ). SuSE supplied updates for the various 1.4.2 packages, but not for the 1.5.0 packages supplied on the 9.3 DVD, e.g. java-1_5_0-sun-plugin-1.5.0_01-5 java-1_5_0-sun-1.5.0_01-5 Now Java version numbers are a bit mysterious, but it looks to me like these packages might be vulnerable. Would anyone like to comment? Thanks, Bob
