Memory Allocation with Excessive Size Value vulnerability in Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ Stomp.

An unauthenticated client that opens a STOMP NIO connection can send header bytes that never terminate which makes the broker buffer them without limit, exhausting the JVM heap. This issue affects Apache ActiveMQ: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ All: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ Stomp: before 5.19.8, from 6.0.0 before 6.2.7.

Users are recommended to upgrade to version 6.2.7 or 5.19.8, which fixes the issue.
