Apple has also released Java for Mac OS X v10.6 Update 13, which fixes multiple vulnerabilities, the most serious of which may allow untrusted Java applets to execute arbitrary code outside the Java sandbox. (These updates bring Java to version 1.6.0_41.)
If your Mac is running 10.6, Java is installed and you should install this update as soon as possible, as Java has become a popular method of exploiting a computer.
Java for Mac OS X v10.6 Update 13 is available for Mac OS X v10.6 and Mac OS X Server v10.6. For more information, see http://support.apple.com/kb/HT5651
