Critical Mac OS X Java Vulnerability Proof of Concept

Critical Mac OS X Java Vulnerability Proof of Concept

Today, Landon Fuller posted a proof-of-concept exploit for an unpatched vulnerability in the Java Runtime Environment currently in use by OS X. While this particular proof-of-concept is meant to be harmless, the vulnerability itself currently affects OS X, including OS X 10.5.7, the latest shipping version of OS X.
