(LiveHacking.Com) – Oracle has released a Critical Patch Update (CPU) for Java SE. The update, which affects Java 5, Java 6 and Java 7, fixes 42 vulnerabilities within Java, the vast majority of which have been rated as the Critical.
“The JDK 7u21 release enables users to make more informed decisions before running Rich Internet Applications (RIAs) by prompting users for permissions before an RIA is run. These permission dialogs include information on the certificate used to sign the application, the location of the application, and the level of access that the application requests,” said Oracle.
According to Oracle Executive Vice President Hasan Rizvi not all the known Java problems have been fixed, but there are no unpatched vulnerabilities that are being actively exploited in the wild.
Java has been prone to security vulnerabilities in the last few years and earlier this year a global hacking campaign managed to infected computers inside hundreds of companies, including Facebook, Apple and Twitter. In light of these threat the US Department of Homeland Security has previously recommended that users disable Java in the browser completely.
Gone are the days when Apple’s Java update would come several months after Oracle’s fixes. As is now becoming the norm, Apple released its updates on the same day as Oracle. Java for OS X 2013-003 and Mac OS X v10.6 Update 15 addresses multiple vulnerabilities Java, some of which could allow an untrusted Java applet to execute arbitrary code outside the Java sandbox. To exploit this a hacker need only convince a user to visit a specially crafted web page with an untrusted Java applet. For more information Apple recommend reading the Java 6 update 45 release notes.
Apple also released a new version of its Safari web browser for OS X Lion v10.7.5, OS X Lion Server v10.7.5 and OS X Mountain Lion v10.8.3. It fixes problems where visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. The problem was an invalid cast that existed in the handling of SVG files. For more information see the Safari 6.0.4 page on Apple’s website.
