Pivotal Application Service Security Overview and Policy

Page last updated:

This document outlines our security policy and is addressed to operators deploying Pivotal Application Service using Pivotal Operations Manager.

For a comprehensive overview of the security architecture of each Application Service component, refer to the PAS Security topic.

How Pivotal Monitors for Security Vulnerabilities

Pivotal receives private reports on vulnerabilities from customers and from field personnel through our secure disclosure process. We also monitor public repositories of software security vulnerabilities to identify newly discovered vulnerabilities that might affect one or more of our products.

How to Report a Vulnerability

Pivotal encourages users who become aware of a security vulnerability in our products to contact Pivotal with details of the vulnerability. Please send descriptions of any vulnerabilities found to security@pivotal.io. Include details about the software and hardware configuration of your system so that we can reproduce the issue.

Note: We encourage use of encrypted email. Our public PGP key is located at http://www.pivotal.io/security.

Notification Policy

Application Service has many customer stakeholders who need to know about security updates. When there is a possible security vulnerability identified for an Application Service component, we do the following:

  1. Assess the impact to Application Service.
  2. If the vulnerability would affect an Application Service component, we schedule an update for the impacted component(s).
  3. Update the affected component(s) and perform system tests.
  4. Announce the fix publicly through the following channels:
    1. Automated notification to end users who have downloaded or subscribed to an Application Service product on Pivotal Network when a new, fixed version is available.
    2. Adding a new post to http://www.pivotal.io/security.

Classes of Vulnerabilities

Attackers can exploit vulnerabilities to compromise user data and processing resources. This can affect data confidentiality, integrity, and availability to different degrees. For vulnerabilities related to Ubuntu provided packages, Pivotal follows Canonical’s priority levels. For other vulnerabilities, Pivotal follows Common Vulnerability Scoring System v3.0 standards when assessing severity.

Pivotal uses Canonical’s Ubuntu distribution of Linux for Application Service Ubuntu stemcells and rootfs. Canonical provides Pivotal with support services allowing us to escalate CVEs that we determine might affect Application Service. In general, Pivotal does not escalate to upstream open source software components or vendors for Medium or Low CVEs that are not yet patched. Application Service can escalate on behalf of a customer for High or Critical CVEs. Application Service customers who are interested in addressing CVEs in Ubuntu that are not yet patched can establish their own support relationship with Canonical.

Pivotal reports the severity of vulnerabilities using the following severity classes:

High

High severity vulnerabilities are those that can be exploited by an unauthenticated or authenticated attacker, from the internet or those that break the guest/host Operating System isolation. The exploitation could result in the complete compromise of confidentiality, integrity, and availability of user data and/or processing resources without user interaction. Exploitation could be leveraged to propagate an internet worm or execute arbitrary code between Virtual Machines and/or the Host Operating System. This rating also applies to those vulnerabilities that could lead to the complete compromise of availability when the exploitation is by a remote unauthenticated attacker from the internet or through a breach of VM isolation.

Moderate

Moderate vulnerabilities are those in which the ability to exploit is mitigated to a significant degree by configuration or difficulty of exploitation, but in certain deployment scenarios could still lead to the compromise of confidentiality, integrity, or availability of user data and/or processing resources.

Low

Low vulnerabilities are all other issues that have a security impact. These include vulnerabilities for which exploitation is believed to be extremely difficult, or for which successful exploitation would have minimal impact.

Release Policy

Application Service schedules regular monthly releases of software in the Application Service Suite to address Low / Medium severity vulnerability exploits. When High severity vulnerability exploits are identified, Application Service releases fixes to software in the Application Service Suite on-demand, with as fast a turnaround as possible.
