Details

Helm Controller denial of service Helm controller is tightly integrated with the Helm SDK. [A vulnerability](https://github.com/helm/helm/security/advisories/GHSA-7hfp-qfw3-5jxh) 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](https://github.com/google/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. ### For more information If you have any questions or comments about this advisory: - Open an issue in any of the affected repositories. - Contact us at the CNCF Flux Channel. ### References - https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=48360 - https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=44996 - https://github.com/helm/helm/security/advisories/GHSA-7hfp-qfw3-5jxh
