The remote Redhat Enterprise Linux 7 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2017:0530 advisory.
RabbitMQ is an implementation of AMQP, the emerging standard for high performance enterprise messaging.
The RabbitMQ server is a robust and scalable implementation of an AMQP broker.
Security Fix(es):
* A resource-consumption flaw was found in RabbitMQ Server, where the lengths_age or lengths_incr parameters were not validated in the management plugin. Remote, authenticated users with certain privileges could exploit this flaw to cause a denial of service by passing values which were too large.
(CVE-2015-8786)
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
