CVE-2018-2796

First published: Sat Apr 14 2018(Updated: )

It was discovered that the implementation of the PriorityBlockingQueue class in the Concurrency component of OpenJDK did not limit the amount of memory allocated when creating object instance from a serialized form. A specially-crafted input could cause a Java application to use an excessive amount of memory when deserialized.
