Affected: Red Hat EAP 7.4.13, Red Hat JBoss Enterprise Application Platform 7.4 for RHEL 8, Red Hat JBoss Enterprise Application Platform 7.4 for RHEL 9, Red Hat JBoss Enterprise Application Platform 7.4 on RHEL 7

A flaw was found in EAP-7 during deserialization of certain classes, which permits instantiation of HashMap and HashTable with no checks on resources consumed. This issue could allow an attacker to submit malicious requests using these classes, which could eventually exhaust the heap and result in a Denial of Service.
