Description Tomas Hoger 2017-10-16 11:39:41 UTC

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

Comment 2 Tomas Hoger 2017-10-17 19:41:22 UTC

Oracle JDK release notes include the following note regarding this fix:

  core-libs/java.util:collections
  Collections use serialization filter to limit array sizes 

  Deserialization of certain collection instances will cause arrays to be
  allocated. The ObjectInputFilter.checkInput() method is now called prior
  to allocation of these arrays. Deserializing instances of ArrayDeque,
  ArrayList, IdentityHashMap, PriorityQueue,
  java.util.concurrent.CopyOnWriteArrayList, and the immutable collections
  (as returned by List.of, Set.of, and Map.of) will call checkInput() with
  a FilterInfo instance whose serialClass() method returns Object[].class.
  Deserializing instances of HashMap, HashSet, Hashtable, and Properties
  will call checkInput() with a FilterInfo instance whose serialClass()
  method returns Map.Entry[].class. In both cases, the
  FilterInfo.arrayLength() method will return the actual length of the array
  to be allocated. The exact circumstances under which the serialization
  filter is called, and with what information, is subject to change in
  future releases.
