Description Vincent Danen 2012-11-14 00:43:17 UTC
IBM Java could allow a remote attacker to execute arbitrary code on the system, caused by insecure use of the java.lang.Class getDeclaredMethods() and java.lang.reflect.AccessibleObject setAccessible() methods. By persuading a victim to visit a malicious Web site containing a specially-crafted applet, an attacker could exploit this vulnerability to bypass sandbox restrictions and execute arbitrary Java code.
