| |
| <h2 id="description">Description</h2> |
| |
| <p>A Denial of Service vulnerability was found in Apache Qpid Broker-J |
| versions 7.0.0-7.0.4 when AMQP protocols 0-8, 0-9 or 0-91 are used to |
| publish messages with size greater than allowed maximum message size limit |
| (100MB by default). The broker crashes due to the defect. AMQP protocols |
| 0-10 and 1.0 are not affected.</p> |
| |
| <h2 id="resolution">Resolution</h2> |
| |
| <p>Users of Broker-J versions 7.0.0-7.0.4 utilizing AMQP protocols 0-8, 0-9 or 0-91 |
| for message publishing must upgrade to version 7.0.5 or later.</p> |
| |
| <h2 id="mitigation">Mitigation</h2> |
| |
| <p>If upgrade of the broker is not possible, the maximum message size limit can be |
| disabled by setting context variable "qpid.max_message_size" to "0" or |
| any negative value. The change can be made either directly in the broker |
| configuration file, or by using management interfaces (for example, REST API) |
| or by sing JVM option -Dqpid.max_message_size=0. A broker restart is required |
| for the change to take effect. |
| Alternatively, the support for AMQP protocols 0-8...0-91 can be |
| removed on AMQP ports. |
| The change can be made either directly in the broker configuration file |
| or by using management interfaces. An example of REST API call |
| restricting AMQP port to support only to AMQP 1.0 and AMQP 0-10 using curl |
| utility is provided below:</p> |
| |
| <p><code>sh |
| curl --user <user-name> -X POST -d '{"protocols":["AMQP_1_0","AMQP_0_10"]}' https://<broker host>:<broker port>/api/latest/port/<port name> |
| </code></p> |
