Description Tomas Hoger 2017-07-17 06:01:12 EDT
A flaw was found in the DisabledAlgorithmConstraints class in the Security component of OpenJDK.  A key size constrained could not have been checked correctly in certain cases, causing weak key to be accepted.  An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.
