Description Tomas Hoger 2021-10-15 13:32:34 UTC

A flaw was found in the way the HashMap and the HashSet classes implementations in the Utility component of OpenJDK validated the load factor value during deserialization.  A specially crafted serialized data stream could cause a Java application to allocate an excessive amount of memory and possibly terminate on out-of-memory condition when deserialized.
