cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.
This patch release of cert-manager 1.15 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.
In addition, since most PEM data parsed by cert-manager comes from
ConfigMaporSecretresources which havea max size limit of approximately 1MB, it's difficult to force cert-manager to parse large amounts of PEM data.
Further information will be published in a security advisory when all supported cert-manager releases have been patched.
In addition, the version of Go used to build cert-manager 1.15 was updated along with the base images, and a Route53 bug fix was backported.

cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.
cert-manager 1.15 promotes several features to beta, including GatewayAPI support (
ExperimentalGatewayAPISupport), the ability to provide a subject in the Certificate that will be used literally in the CertificateSigningRequest (LiteralCertificateSubject) and the outputting of additional certificate formats (AdditionalCertificateOutputFormats).Community

It incorrectly copies the critical field from the CSR.v1.14.0, the Helm chart for this version was found to use the wrong OCI image for thecainjectorDeployment,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.startupapicheckimage in namespaces other than cert-manager.cmctl experimental installto 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
otherNametype with aUTF-8value, such as the User Principal Name orsAMAccountName.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:
The feature is still in alpha stage and requires you to enable the
OtherNamefeature 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.algorithmsto specify encryption and MAC algorithms for PKCS.🤝 Community
