UPDATE: Apple just released Java for OS X 2012-001 and Java for Mac OS X 10.6 Update 7, which addresses this vulnerability. You can download the new versions from http://www.apple.com/support/downloads. More information about the release notes at http://www.oracle.com/technetwork/java/javase/releasenotes-136954.html

If you own a MacOS computer, you might want to disable java for a while until Oracle develops a patch to solve CVE-2012-0507 vulnerability, because there is a Blackhole Exploit Kit version in the wild exploiting this vulnerability and it also can be exploited using metasploit.

If you want to disable java plugins in your MacOS computer, Marcus J. Carey created a video showing how to do it.
