How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream dex-k8s-authenticator package and not the dex-k8s-authenticator package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Due to unbounded alias chasing, a maliciously crafted YAML file can cause the system to consume significant system resources. If parsing user input, this may be used as a denial of service vector.
