Description
OpenStack Orchestration (heat) is a template-driven engine used to specify and deploy configurations for Compute, Storage, and OpenStack Networking. The service can be used to automate post-deployment actions, which in turn allows automated provisioning of infrastructure, services, and applications. Additionally, Orchestration can be integrated with Telemetry alarms to implement auto-scaling for certain infrastructure resources.
Security Fix(es):
- An access-control flaw was found in the OpenStack Orchestration (heat) service where a service log directory was improperly made world readable. A malicious system user could exploit this flaw to access sensitive information. (CVE-2017-2621)
- An information-leak vulnerability was found in the OpenStack Orchestration (heat) service. Launching a new stack with a local URL resulted in a detailed error message, allowing an authenticated user to conduct network discovery and reveal the details of internal network services. (CVE-2016-9185)
Red Hat would like to thank Hans Feldt (Ericsson) for reporting CVE-2017-2621.
