Details

As written in the advisory (Markdown source, shown as plain text).

# Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-r4pg-vg54-wxx4. This link is maintained to preserve external references. # Original Description A flaw was found in the cert-manager package. This flaw allows an attacker who can modify PEM data that the cert-manager reads, for example, in a Secret resource, to use large amounts of CPU in the cert-manager controller pod to effectively create a denial-of-service (DoS) vector for the cert-manager in the cluster.
