It was discovered that the RMI (Java Remote Method Invocation) server implementation in the JMX (Java Management Extensions) component of OpenJDK did not restrict which classes can be deserialized when deserializing authentication credentials. A remote unauthenticated attacker able to connect to a JMX port could possibly use this flaw trigger deserialization flaws.

A stack overflow vulnerability was found in nan functions that could cause applications which process long strings with the nan function to crash or, potentially, execute arbitrary code.
