Polish security firm Security Explorations has sent an advisory, with a proof-of-concept exploit, to Oracle today (Friday 31 AUG) specific to a vulnerability they discovered in the Java 7 security update released Thursday.  This newly reported vulnerability can be exploited to escape the Java sandbox and execute arbitrary code on the underlying system.
Standby for more on this one, no word yet from Oracle regarding their remediation plans.

As Rapid7's Tod Beardsley has said: "As it happens, very few websites rely on Java for dynamic content. Java isn't relied on nearly as much as Javascript and Flash. Most people can disable their Java browser plugin and not really notice the difference."

What mitigations are you utilizing to protect yourselves? Going so far as disabling Java all together? Feedback welcome via comments.

See Scott's post from yesterday for the original advisory details.
