activemq-stomp: Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ Stomp: Unbounded header buffer in STOMP NIO codec

An unbounded memory allocation flaw was found in the STOMP NIO codec of Apache ActiveMQ Classic. An unauthenticated remote client can open a STOMP NIO connection and send an unterminated header, causing the broker to buffer input without limit and potentially exhaust the JVM heap, resulting in a...

Denial Of Service (DoS)

Apache ActiveMQ is vulnerable to a Memory Allocation with Excessive Size Value vulnerability. The vulnerability is due to improper handling of non-terminating STOMP header bytes, which allows an unauthenticated attacker to send an excessive amount of header data over a STOMP NIO connection, causi...
