Description Tomas Hoger 2020-01-15 12:59:17 UTC
It was discovered that the DatagramChannelImpl class in the Networking component of OpenJDK failed to completely enforce the limit of the number of datagram sockets (set using the sun.net.maxDatagramSockets system property) that can be created by a code running with the Java sandbox restrictions.  An untrusted Java code could use this flaw to bypass the intended Java sandbox restriction.
