Hello All, We had yet another look into Oracle's Java SE 7 software that was released by the company on Feb 19, 2013. As a result, we have discovered two new security issues (numbered 54 and 55), which when combined together can be successfully used to gain a complete Java security sandbox bypass in the environment of Java SE 7 Update 15 (1.7.0_15-b03). Following our Disclosure Policy [1], we provided Oracle with a brief technical description of the issues found along with a working Proof of Concept code that illustrates their impact. Both new issues are specific to Java SE 7 only. They allow to abuse the Reflection API in a particularly interesting way. Without going into further details, everything indicates that a ball is in Oracle's court. Again. Thank you.
