v1.16.3

Compare Source

cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.

v1.16.3 is a patch release mainly focused around bumping dependencies to address reported CVEs: CVE-2024-45337 and CVE-2024-45338.

We don't believe that cert-manager is actually vulnerable; this release is instead intended to satisfy vulnerability scanners.

It also includes a bug fix to the new renewBeforePercentage field. If you were using renewBeforePercentage, see PR #​7421 for more information.

Bug

• Bump golang.org/x/net and golang.org/x/crypto to address CVE-2024-45337 and CVE-2024-45338 (#​7485, @​erikgb)
• Fix the behaviour of renewBeforePercentage to comply with its spec (#​7441, @​cert-manager-bot)

Other

• Bump go to 1.23.4 (#​7489, @​erikgb)
• Bump base images to latest available (#​7508, @​SgtCoDFish)

v1.16.2

Compare Source

cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.

This patch release of cert-manager 1.16 makes several changes to how PEM input is validated, adding maximum sizes appropriate to the type of PEM data which is being parsed.

This is to prevent an unacceptable slow-down in parsing specially crafted PEM data. The issue was found by Google's OSS-Fuzz project.

The issue is low severity; to exploit the PEM issue would require privileged access which would likely allow Denial-of-Service through other methods.

Note also that since most PEM data parsed by cert-manager comes from ConfigMap or Secret resources which have a max size limit of approximately 1MB, it's difficult to force cert-manager to parse large amounts of PEM data.

Further information is available in GHSA-r4pg-vg54-wxx4

In addition, the version of Go used to build cert-manager 1.16 was updated along with the base images.

Changes by Kind

Bug or Regression

• Set a maximum size for PEM inputs which cert-manager will accept to remove possibility of taking a long time to process an input (#​7401, @​SgtCoDFish)

📜Changes since v1.16.0

Bug or Regression

• BUGFIX: Helm schema validation: the new schema validation was too strict for the "global" section. Since the global section is shared across all charts and sub-charts, we must also allow unknown fields. (#​7348, @inteon)
• BUGFIX: Helm will now accept percentages for the podDisruptionBudget.minAvailable and podDisruptionBudget.maxAvailable values. (#​7345, @inteon)
• Helm: allow enabled to be set as a value to toggle cert-manager as a dependency. (#​7356, @inteon)
• BUGFIX: A change in v1.16.0 caused cert-manager's ACME ClusterIssuer to look in the wrong namespace for resources required for the issuance (e.g. credential Secrets). This is now fixed in v1.16.1. (#​7342, @inteon)

⚠️ Known issues

1. Helm Chart: JSON schema prevents the chart being used as a sub-chart on Rancher RKE.
2. ACME DNS01 ClusterIssuer fail while loading credentials from Secret resources.

❗ Breaking changes

1. Helm schema validation may reject your existing Helm values files if they contain typos or unrecognized fields.
2. Venafi Issuer may fail to renew certificates if the requested duration conflicts with the CA’s minimum or maximum policy settings in Venafi.
3. Venafi Issuer may fail to renew Certificates if the issuer has been configured for TPP with username-password authentication.

Bug or Regression

• Adds support (behind a flag) to use a domain qualified finalizer. If the feature is enabled (which is not by default), it should prevent Kubernetes from reporting: metadata.finalizers: "finalizer.acme.cert-manager.io": prefer a domain-qualified finalizer name to avoid accidental conflicts with other finalizer writers (#​7273, @jsoref)

📜 Changes since v1.14.1

Bug or Regression

• BUGFIX: cert-manager CA and SelfSigned issuers incorrectly copied the critical flag from the CSR instead of re-calculating that field themselves. (#​6727, @​jetstack-bot)
• Helm: Fix a bug in the logic that differentiates between 0 and an empty value. (#​6729, @​jetstack-bot)

Other (Cleanup or Flake)

• Bump golang to 1.21.7 (#​6735, @​jetstack-bot)

v1.14.1

Compare Source

cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.

cert-manager 1.14 brings a variety of features, security improvements and bug fixes, including: support for creating X.509 certificates with "Other Name" fields, and support for creating CA certificates with "Name Constraints" and "Authority Information Accessors" extensions.

⚠️ This version has known issues. Please install v1.14.2 instead.

⚠️ Known Issues (please install v1.14.2)

• ACME Issuer (Let's Encrypt): wrong certificate chain may be used if preferredChain is configured: see release docs for more info and mitigations
• In cert-manager v1.14.0 and v1.14.1, the CA and SelfSigned issuers issue certificates with SANs set to non-critical even when the subject is empty. It incorrectly copies the critical field from the CSR.

📜 Changes since v1.14.0

Bug or Regression

• Fix broken cainjector image value in Helm chart (#​6693, @​SgtCoDFish)
• Fix bug in cmctl namespace detection which prevented it being used as a startupapicheck image in namespaces other than cert-manager. (#​6706, @​inteon)
• Fix bug in cmctl which caused cmctl experimental install to panic. (#​6706, @​inteon)

• During the release of v1.14.0, the Helm chart for this version was found to use the wrong OCI image for the cainjector Deployment,
  which caused the Helm installation to fail.
  In order to complete the release, the cert-manager team have manually updated the Helm chart for this version,
  which contains all the Helm chart fixes which are in v1.14.1.
• A bug in cmctl namespace detection prevents it being used as a startupapicheck image in namespaces other than cert-manager.
• A bug in cmctl causes cmctl experimental install to panic.

🔧 Breaking Changes

The startupapicheck job uses a new OCI image called "startupapicheck", instead of the ctl image.
If you run in an environment in which images cannot be pulled, be sure to include the new image.

The KeyUsage and BasicConstraints extensions will now be encoded as critical in the CertificateRequest's CSR blob.

🗺️ Major Themes

New X.509 Features

The cert-manager Certificate resource now allows you to configure a subset of "Other Name" SANs,
which are described in the Subject Alternative Name section of RFC 5280 (on page 37).

We specifically support any otherName type with a UTF-8 value, such as the User Principal Name or sAMAccountName.
These are useful when issuing unique certificates for authenticating with LDAP systems such as Microsoft Active Directory.
For example you can create certificates with this block in the spec:

  otherNames:
    - oid: 1.3.6.1.4.1.311.20.2.3 # UPN OID
      utf8Value: [email protected]

The feature is still in alpha stage and requires you to enable the OtherName feature flag in the controller and webhook components.

New CA certificate Features

You can now specify the X.509 v3 Authority Information Accessors extension,
with URLs for certificates issued by the CA issuer.

Users can now use name constraints in CA certificates.
To know more details on name constraints check out RFC section https://datatracker.ietf.org/doc/html/rfc5280#section-4.2.1.10

Security

An ongoing security audit of the cert-manager code revealed some weaknesses which we have addressed in this release,
such as using more secure default settings in the HTTP servers that serve metrics, healthz and pprof endpoints.
This will help mitigate denial-of-service attacks against those important services.

All the cert-manager containers are now configured with read only root file system by default,
to prevent unexpected changes to the file system of the OCI image.

And it is now possible to configure the metrics server to use HTTPS rather than HTTP,
so that clients can verify the identity of the metrics server.

Other

The liveness probe of the cert-manager controller Pod is now enabled by default.

There is a new option .spec.keystores.pkcs12.algorithms to specify encryption and MAC algorithms for PKCS.
