REDHAT-BUG-2041801: Medium severity openjdk 8 vulnerability
It was discovered that the ObjectInputStream class implementation in the Serialization component of OpenJDK did not check superclasses against the deserialization filter (defined via jdk.serialFilter system or security property) in cases when those classes were available locally and not included in the serialized stream. A specially-crafted serialized stream could possibly use this flaw to bypass class deserialization restrictions.
