CVE-2017-15699
Description
From CVE.org
A Denial of Service vulnerability was found in Apache Qpid Dispatch Router versions 0.7.0 and 0.8.0. To exploit this vulnerability, a remote user must be able to establish an AMQP connection to the Qpid Dispatch Router and send a specifically crafted AMQP frame which will cause it to segfault and shut down.
Mitigation
To protect against this vulnerability, users need to ensure the interconnect route endpoints are protected by authentication. Please refer to official documentation on how to secure the endpoints: https://access.redhat.com/documentation/en-us/red_hat_jboss_amq/7.0/html-single/using_amq_interconnect/#security-1
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory)
An attacker could provide unexpected values and cause a program crash or arbitrary control of resource allocation, leading to excessive consumption of resources such as memory and CPU.
Confidentiality
Technical Impact: Read Memory; Read Files or Directories
An attacker could read confidential data if they are able to control resource references.
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
An attacker could use malicious input to modify data or possibly alter control flow in unexpected ways, including arbitrary command execution.
