Ops Manager Security Overview and Policy
Page last updated:
This document outlines VMware’s security policy and is addressed to operators deploying VMware Tanzu Operations Manager (Ops Manager).
For a comprehensive overview of the security architecture of each VMware Tanzu Application Service for VMs (TAS for VMs) component, see TAS for VMs Security.
VMware receives private reports on vulnerabilities from customers and from field personnel through VMware’s secure disclosure process. VMware also monitors public repositories of software security vulnerabilities to identify newly discovered vulnerabilities that might affect one or more of VMware’s products.
VMware encourages users who become aware of a security vulnerability in VMware’s products to contact VMware with details of the vulnerability. Please send descriptions of any vulnerabilities found to firstname.lastname@example.org. Include details about the software and hardware configuration of your system so that VMware can reproduce the issue.
Note: VMware encourages use of encrypted email. For VMware’s public PGP key, see Pivotal Application Security Team on the VMware Tanzu website.
Ops Manager has many customer stakeholders who need to know about security updates. When there is a possible security vulnerability identified for an Ops Manager component, VMware does the following:
Assess the impact to Ops Manager.
If the vulnerability would affect an Ops Manager component, VMware schedules an update for the impacted components.
Update the affected components and perform system tests.
Announce the fix publicly through the following channels:
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, VMware follows Canonical’s priority levels. For other vulnerabilities, VMware follows Common Vulnerability Scoring System v3.0 standards when assessing severity. For more information about Canonical’s priority levels, see CVE Priority in Ubuntu CVE Tracker. For more information about Common Vulnerability Scoring System v3.0 standards, see Common Vulnerability Scoring System version 3.1: Specification Document on the FIRST website.
VMware uses Canonical’s Ubuntu distribution of Linux for Ops Manager Ubuntu stemcells and rootfs. Canonical provides VMware with support services allowing VMware to escalate CVEs that VMware determine might affect Ops Manager. In general, VMware does not escalate to upstream open source software components or vendors for Medium or Low CVEs that are not yet patched. Ops Manager can escalate on behalf of a customer for High or Critical CVEs. Ops Manager customers who are interested in addressing CVEs in Ubuntu that are not yet patched can establish their own support relationship with Canonical through the Support page on the Ubuntu website.
VMware reports the severity of vulnerabilities using the following severity classes:
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 (VMs) 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.
Medium 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 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.
VMware schedules regular monthly releases of software to address Low and Medium severity vulnerability exploits. When High severity vulnerability exploits are identified, VMware releases fixes to software as quickly as possible.
