Researchers at Core Security Technologies have uncovered a security hole that could allow someone to circumvent the application sandbox restrictions of Mac OS X. Apple announced earlier this month that all applications submitted to the Mac App store must implement sandboxing as of March 1, 2012. Apple has argued that sandboxing limits the resources applications can access and makes it more difficult for malware to compromise systems. Researchers say they warned Apple in September that they had warned Apple about a vulnerability in their sandboxing approach. The vulnerability was patched in an iOS update released Nov. 10.
