Ecosyste.ms: Advisories

An open API service providing security vulnerability metadata for many open source software ecosystems.

Security Advisories: GSA_kwCzR0hTQS1wMmc3LXh3dnItcnJ3M84AAu1q

Helm Controller denial of service

Helm controller is tightly integrated with the Helm SDK. A vulnerability found in the Helm SDK allows for specific data inputs to cause high memory consumption, which in some platforms could cause the controller to panic and stop processing reconciliations.

Impact

In a shared cluster multi-tenancy environment, a tenant could create a HelmRelease that makes the controller panic, denying all other tenants from their Helm releases being reconciled.

Credits

The initial crash bug was reported by oss-fuzz. The Flux Security team produced the first exploit and worked together with the Helm Security team to ensure that both projects were patched timely.
