Java for Snow Leopard, Lion and Mountain Lion updated over security
Tuesday, October 15, 2013 @ 10:30pm
| For the fifth time this year, Apple has had to issue an update to Java for all three supported versions of OS X: Snow Leopard (10.6), Lion (10.7) and Mountain Lion (10.8). As has become the norm, the update was issued due to the discovery of "multiple vulnerabilities" in Java 1.6.0_51. The cross-platform development technology has been updated to version 1.6.0_65, and is referred to in Software Update as "Java for Mac OS X 10.6 Update 17" for Snow Leopard and "Java for OS X 2013-005" for newer systems.
The flaws vary in risk, but the most serious of the problems "may allow an untrusted Java applet to execute arbitrary code outside the Java sandbox. Visiting a web page containing a maliciously crafted untrusted Java applet may lead to arbitrary code execution with the privileges of the current user," report Apple. The company has been forced to disable Java multiple times owing to serious security issues over the past two years, and stopped distributing Java with new Macs in 2010 over the same sort of issues.
Users who are dependent on Java for things like web applications and games must stay ever-vigilant for new updates, either directly from Oracle (the current maintainer of Java following its purchase of Sun Microsystems) or through Apple's Software Update. Apple's software now automatically disables Java entirely if it hasn't been used in the past 30 days, and will warn users of risks or outright block the use of outdated versions of Java.
The new update notes that it is uninstalling the (outdated) Apple-provided Java applet plug-in from all web browsers in favor of the new install. Java has risen to become by far the most popular source of vulnerabilities for malware on the Mac to exploit, though Apple's aggressive efforts to disable it unless the very latest version is installed and used has kept incidents of malware very low and still rare.
The latest release notes for Java 1.6.0_65 reveal that it plugs some 38 separately-reported issues. The update is also available through Apple's Support Downloads web page.
