Apple has a poor history here, often failing to provide OS X security fixes for flaws fixed on other platforms days, weeks, or even months earlier. We’ve seen Mac users exposed to known vulnerabilities in WebKit (Safari), Samba (Windows file sharing), DNS (networking), MDNS (Bonjour), Apache (web server), Java, and more. This is an extremely serious problem, and one Apple is rightly criticized for. All Mac users are at risk due to the Java vulnerability, and should immediately take actions to protect themselves. Had Apple issued a patch with everyone else, we wouldn’t be so exposed.
