Description Tomas Hoger 2016-07-15 08:00:04 EDT

A flaw was found in the way the dropArguments() method of the MethodHandles class in the Libraries component of OpenJDK handled its valueTypes argument.  As it did not create a copy of the list, caller could modify it after it was checked by the dropArguments() method.  An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

Comment 1 Tomas Hoger 2016-07-20 03:41:30 EDT

Public now via Oracle CPU July 2016, fixed in Oracle JDK 8u101.
