Allocation of Resources Without Limits or Throttling


Severity High
Score 7.5/10


Helm is a tool for managing Charts, pre-configured Kubernetes resources. Versions prior to 3.10.3 are subject to Uncontrolled Resource Consumption, resulting in Denial of Service. Input to functions in the "_strvals_" package can cause a stack overflow. In Go, a stack overflow cannot be recovered from. Applications that use functions from the "_strvals_" package in the Helm SDK can have a Denial of Service attack when they use this package and it panics. SDK users can validate strings supplied by users won't create large arrays causing significant memory usage before passing them to the "_strvals_" functions.
