NVD Description

Note: Versions mentioned in the description apply only to the upstream helm-zsh-completion package and not the helm-zsh-completion package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

Helm is a tool for managing Charts. Charts are packages of pre-configured Kubernetes resources. Fuzz testing, provided by the CNCF, identified input to functions in the strvals package that can cause an out of memory panic. The strvals package contains a parser that turns strings in to Go structures. The strvals package converts these strings into structures Go can work with. Some string inputs can cause array data structures to be created causing an out of memory panic. Applications that use the strvals package in the Helm SDK to parse user supplied input can suffer a Denial of Service when that input causes a panic that cannot be recovered from. The Helm Client will panic with input to --set, --set-string, and other value setting flags that causes an out of memory panic. Helm is not a long running service so the panic will not affect future uses of the Helm client. This issue has been resolved in 3.9.4. SDK users can validate strings supplied by users won't create large arrays causing significant memory usage before passing them to the strvals functions.
