A flaw was found in Helm v3. In affected versions of Helm, a specially crafted chart archive file can cause Helm to use all available memory and have an out of memory (OOM) termination. A chart archive file can be crafted in a manner where it expands to be significantly larger uncompressed than compressed (for example, >800x difference). When Helm loads this specially crafted chart, memory can be exhausted causing the application to terminate.

Description OSIDB Bzimport 2025-04-09 23:01:15 UTC
Helm is a tool for managing Charts. A chart archive file can be crafted in a manner where it expands to be significantly larger uncompressed than compressed (e.g., >800x difference). When Helm loads this specially crafted chart, memory can be exhausted causing the application to terminate. This issue has been resolved in Helm v3.17.3.
