v1.17.0

Compare Source

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

v1.17.0 is a feature release with several improvements, including:

• A helpful compliance change to RSA signatures on certificates
• An easier way to specify passwords for PKCS#12 and JKS keystores
• A few feature flag promotions (and a deprecation)
• Dependency bumps and other smaller improvements

Major Themes

RSA Certificate Compliance

The United States Department of Defense published a memo in 2022 which introduced some requirements on the kinds of cryptography they require to be supported in software they use.

In effect, the memo requires that software be able to support larger RSA keys (3072-bit and 4096-bit) and hashing algorithms (SHA-384 at a minimum).

cert-manager supported large RSA keys long before the memo was published, but a quirk in implementation meant that cert-manager always used SHA-256 when signing with RSA.

In v1.17.0, cert-manager will choose a hash algorithm based on the RSA key length: 3072-bit keys will use SHA-384, and 4096-bit keys will use SHA-512. This matches similar behavior already present for ECDSA signatures.

Our expectation is that this change will have minimal impact beyond a slight increase to security and better compliance; we're not aware of Kubernetes based environments which support RSA 2048 with SHA-256 but fail with RSA 4096 and SHA-512. However, if you're using larger RSA keys, you should be aware of the change.

Easier Keystore Passwords for PKCS#12 and JKS

Specifying passwords on PKCS#12 and JKS keystores is supported in cert-manager
for compatibility reasons with software which expects or requires passwords to be set; however, these passwords are not relevant to security and never have been in cert-manager.

The initial implementation of the keystores feature required these "passwords" to be stored in a Kubernetes secret, which would then be read by cert-manager when creating the keystore after a certificate was issued. This is cumbersome, especially when many passwords are set to default values such as changeit or password.

In cert-manager v1.17, it's now possible to set a keystore password using a literal string value inside the Certificate resource itself, making this process much easier with no change to security.

For example:

apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
  name: my-cert-password
spec:
  secretName: my-cert-password
  issuerRef:
    name: my-issuer
    kind: ClusterIssuer
  keystores:
    jks:
      create: true
      password: "abc123"
    pkcs12:
      create: true
      password: "password"
  dnsNames:
  - example.com

The new password field is mutually exclusive with the passwordSecretRef field, so be sure to only set one.

Feature Flag Promotions / Deprecations

cert-manager's feature flags allow for easier testing and adoption of new features with a reduced risk of breaking changes. In cert-manager v1.17, two feature gates have been promoted to "beta", and as such are now enabled by default in all installations:

• NameConstraints, allowing users to specify the name constraints extension which can be helpful when creating CA certificates for private PKI
• UseDomainQualifiedFinalizer, which stops a Kubernetes warning from being printed in logs

In addition, we added a new feature gate: CAInjectorMerging, which intelligently combines certificates used by the CAInjector component, making it safer to use when issuing certificates are rotated. If you're making heavy use of the CA injector, you should consider enabling this feature gate.

Finally, we deprecated the ValidateCAA feature gate which will be removed entirely in cert-manager v1.18.0. This feature gate aimed to validate the CAA DNS record during ACME issuance, but has seen low adoption and limited testing since its introduction back in 2019.

Other Changes

There are many other PRs which were merged in this release cycle and we'd encourage you to read the release notes below. One PR that's worth highlighting is a change to add more structured logging information to certain log lines.

If you were previously filtering logs using grep or similar tools (which is highly discouraged!) be aware that some log lines have changed format.

Feature

• Potentially BREAKING: The CA and SelfSigned issuers now use SHA-512 when signing with RSA keys 4096 bits and above, and SHA-384 when signing with RSA keys 3072 bits and above. If you were previously using a larger RSA key as a CA, be sure to check that your systems support the new hash algorithms. (#​7368, @​SgtCoDFish)
• Add CAInjectorMerging feature gate to the ca-injector, enabling this will change the behaviour of the ca-injector to merge in new CA certificates instead of outright replacing the existing one. (#​7469, @​ThatsMrTalbot)
• Added image pull secrets to deployments when service accounts aren't created (#​7411, @​TheHenrick)

Bug or Regression

• 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 (eg. credential Secrets). This is now fixed in v1.16.1+ and v1.17.0+ (#​7339, @​inteon)

• SECURITY (low risk): Limit maximum allowed PEM size to prevent potential DoS in cert-manager controller from attacker-controlled PEM. See GHSA-r4pg-vg54-wxx4 (#​7400, @​SgtCoDFish)
• The Certificate object will no longer create CertificateRequest or Secret objects while being deleted (#​7361, @​ThatsMrTalbot)
• The issuer will now more quickly retry when its linked Secret is updated to fix an issue that caused a high back-off timeout. (#​7455, @​inteon)
• Upgrades Venafi vCert library fixing a bug which caused the RSA 3072 bit key size for TPP certificate enrollment to not work. (#​7498, @​inteon)

Other (Cleanup or Flake)

• ⚠️ Potentially BREAKING: Log messages that were not structured have now been replaced with structured logs. If you were matching on specific log strings, this could break your setup. (#​7461, @​inteon)

• Remove Neither --kubeconfig nor --master was specified warning message when the controller and the webhook services boot (#​7457, @​Peac36)
• Move 'live' DNS tests into a separate package to contain test flakiness and improve developer UX (#​7530, @​SgtCoDFish)

v1.16.4

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.

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.

❗ 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.
