GHSA-p2g7-xwvr-rrw3

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.
