Migrating to Mesh CA from Istio CA with little or no downtime.

Migrating to Anthos Service Mesh certificate authority (Mesh CA) from Istio CA (also known as Citadel) requires migrating the root of trust. Prior to Anthos Service Mesh 1.10, if you wanted to migrate from Istio on to Anthos Service Mesh with Mesh CA, you needed to schedule downtime because Anthos Service Mesh was not able to load multiple root certificates, which interrupted mutual TLS (mTLS) traffic during the migration.

With Anthos Service Mesh 1.10 and higher, you can install a new in-cluster control plane with an option that distributes the Mesh CA root of trust to all proxies. After switching to the new control plane and restarting workloads, all proxies are configured with both the Istio CA and Mesh CA root of trust. Next, you install a new in-cluster control plane that has Mesh CA enabled. As you switch workloads over to the new control plane, mTLS traffic isn't interrupt. For details, see Migrating to Mesh CA.

Multi-cluster support for GKE on-prem Beta

Anthos Service Mesh now supports multi-cluster meshes when running on GKE on-prem. For more information, see Add clusters to Anthos Service Mesh on-prem.

New flags for the install_asm script

The install_asm script was enhanced to provide you with more granular control over the changes that the script makes on your project and GKE on Google Cloud cluster. For more information, see the Enablement flags section in the documentation for the script.

Third-party add-ons removed from all profiles

The Prometheus, Grafana, and Kiali add-ons were removed from all Anthos Service Mesh profiles. For information on why the add-ons were removed, see Reworking our Addon Integrations. Installation of these third-party add-ons was removed from the 1.8 IstioOperator API, which means that they can't be installed with the istioctl install command. For information on installing a demo version of the add-ons, see Integrating with third-party add-ons.

Note that by default, metrics are still exported to Prometheus in the asm-multicloud profile. You can optionally enable metrics export to Prometheus in the asm-gcp-multiproject profile.

Fixes the security issue, ISTIO-SECURITY-2020-007, with the same fixes as Istio 1.6.4. For information, see the Istio release notes.

Description

The vulnerability affects Anthos Service Mesh (ASM) versions 1.4.0 to 1.4.10, 1.5.0 to 1.5.5, and 1.6.4 whether running in Anthos clusters on VMware or on GKE, potentially exposing your application to Denial of Service (DOS) attacks. This vulnerability is referenced in these publicly disclosed Istio security bulletins:

• ISTIO-SECURITY-2020-007:
  • CVE-2020-12603 (CVSS score 7.0, High): Envoy through 1.14.1 may consume excessive amounts of memory when proxying HTTP/2 requests or responses with many small (e.g., 1 byte) data frames.
  • CVE-2020-12605 (CVSS score 7.0, High): Envoy through 1.14.1 may consume excessive amounts of memory when processing HTTP/1.1 headers with long field names or requests with long URLs.
  • CVE-2020-8663 (CVSS score 7.0, High): Envoy version 1.14.1 or earlier may exhaust file descriptors and/or memory when accepting too many connections.
  • CVE-2020-12604 (CVSS score 7.0, High): Envoy through 1.14.1 is susceptible to increased memory usage in the case where an HTTP/2 client requests a large payload but does not send enough window updates to consume the entire stream and does not reset the stream. The attacker can cause data associated with many streams to be buffered forever.

Mitigation

If you use ASM 1.6.4: * Apply the additional configuration changes specified in ISTIO-SECURITY-2020-007 to prevent Denial of Service (DOS) attacks on your mesh.

If you use ASM 1.4.0 to 1.4.10 or 1.5.0 to 1.5.5: * Upgrade your clusters to ASM 1.4.10-asm.3 or ASM 1.5.7-asm.0 as soon as possible and apply the additional configuration changes specified in ISTIO-SECURITY-2020-007 to prevent Denial of Service (DOS) attacks on your mesh.

Fixes the security issue, CVE-2020-11080, with the same fixes as OSS Istio 1.5.5. The security fixes were backported to ASM 1.4.10.

Description

A vulnerability affecting the HTTP/2 library used by Envoy has been fixed and publicly disclosed (c.f. Denial of service: Overly large SETTINGS frames ).

CVE-2020-11080: By sending a specially crafted packet, an attacker could cause the CPU to spike at 100%. This could be sent to the ingress gateway or a sidecar.

Mitigation

HTTP/2 support could be disabled on the Ingress Gateway as a temporary workaround using the following configuration. HTTP/2 support at ingress can only be disabled if you are not exposing HTTP/2 services that cannot fallback to HTTP/1.1 through ingress. Note that gRPC services cannot fallback to HTTP/1.1.

1.5.x

1.5.4-asm.2

1.5.4-asm.2 is now available.

Security fixes

1.5.4-asm.2 contains all the same security fixes that are in Anthos Service Mesh 1.4.

Beta release of the Anthos CLI

The Anthos CLI simplifies the installation of Anthos Service Mesh. You can use the Anthos CLI to:

• Create a new cluster that meets the Anthos Service Mesh cluster requirements and install Anthos Service Mesh. See Installing Anthos Service Mesh on a new cluster using the Anthos CLI.
• Update an existing cluster with the options that Anthos Service Mesh requires and install Anthos Service Mesh. See Installing Anthos Service Mesh on an existing cluster using the Anthos CLI.

Port change for automatic sidecar injection

If you are installing Anthos Service Mesh on a private cluster, you must add a firewall rule to open port 15017 if you want to use automatic sidecar injection. In Anthos Service Mesh 1.4, the port used for automatic sidecar injection is 9443.

If you don't add the firewall rule and automatic sidecar injection is enabled, you get an error when you deploy workloads. For details on adding a firewall rule, see Adding firewall rules for specific use cases.

The alpha authentication policy is deprecated

See Updating to the beta security policies for more information.

IstioOperator API replaces IstioControlPlane API

The alpha IstioControlPlane API has been replaced by the IstioOperator API. You must use the IstioOperator API in YAML files to enable optional features when you install Anthos Service Mesh.

Istio CNI plugin is supported

By default Anthos Service Mesh injects an initContainer, istio-init, in pods deployed in the mesh. The istio-init container sets up the pod network traffic redirection to/from the sidecar proxy. This requires the user or service-account deploying pods to the mesh to have sufficient Kubernetes RBAC permissions to deploy containers with the NET_ADMIN and NET_RAW capabilities. Requiring users to have elevated Kubernetes RBAC permissions is problematic for some organization's security compliance. The Istio Container Network Interface (CNI) plugin is a replacement for the istio-init container that performs the same networking functionality but without requiring users to enable elevated Kubernetes RBAC permissions.

The Istio CNI plugin performs the mesh pod traffic redirection in the Kubernetes pod lifecycle's network setup phase, thereby removing the requirement for the NET_ADMIN and NET_RAW capabilities for users deploying pods into the mesh. The Istio CNI plugin replaces the functionality provided by the istio-init container.

Enabling pod security policies no longer needed

SDS security was improved by merging Node Agent with Pilot Agent as Istio Agent and removing cross-pod UDS, which no longer requires users to deploy Kubernetes pod security policies for UDS connections.
