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
orSecret
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.
