Apple has released Java for Mac OS X 10.6 Update 3, which updates Java SE 6 to version 1.6.0_22. The new release is primarily aimed at resolving security issues; among them:
“Multiple vulnerabilities exist in Java 1.6.0_20, the most serious of which 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. These issues are addressed by updating to Java version 1.6.0_22.”
The new release is available through Software Update or this download link.
