The update addresses a number of flaws in Java for systems running MacOS X 10.4 'Tiger' and 10.5 'Leopard,' including a number of security flaws which could allow for such actions as elevation of privileges and remote code execution.

Among the security holes being patched are a flaw which could allow an attacker to remotely execute code by way of a malformed Java applet embedded in a web page, as well as another flaw which could allow an untrusted applet to elevate user privileges.
The company is recommending that users of both OS X Tiger and Leopard install the update.
The Java update comes just days after researchers issued yet another warning to Mac users over the appearance of yet another malicious Trojan aimed at OS X.
Security vendors have worried in recent months that Mac OS X users who are not generally accustomed to dealing with malware threats could be in increasing danger as more attacks emerge.
