Summary

The JNLP SecurityManager in IcedTea (IcedTea.so) 1.7 before 1.7.7, 1.8 before 1.8.4, and 1.9 before 1.9.4 for Java OpenJDK returns from the checkPermission method instead of throwing an exception in certain circumstances, which might allow context-dependent attackers to bypass the intended security policy by creating instances of ClassLoader.
