Apple has posted two new Mac OS X Java updates. The first, Java for Mac OS X 10.6 Update 4, upgrades Java SE 6 in Snow Leopard to v1.6.0_24. Apple is vague on details, but does mention that the release improves "compatibility, security, and reliability." Security-wise it copes with "multiple vulnerabilities," the most dangerous of which might allow an untrusted applet to run code outside the Java sandbox.
