Details

Helm vulnerable to denial of service through schema file Fuzz testing, by Ada Logics and sponsored by the CNCF, identified input to functions in the `_chartutil_` package that can cause a segmentation violation. Applications that use functions from the `_chartutil_` package in the Helm SDK can have a Denial of Service attack when they use this package and it panics. ### Impact The `_chartutil_` package contains a parser that loads a JSON Schema validation file. For example, the Helm client when rendering a chart will validate its values with the schema file. The `_chartutil_` package parses the schema file and loads it into structures Go can work with. Some schema files can cause array data structures to be created causing a memory violation. Applications that use the `_chartutil_` package in the Helm SDK to parse a schema file can suffer a Denial of Service when that input causes a panic that cannot be recovered from. The Helm Client will panic with a schema file that causes a memory violation panic. Helm is not a long running service so the panic will not affect future uses of the Helm client. ### Patches This issue has been resolved in 3.10.3. ### Workarounds SDK users can validate schema files that are correctly formatted before passing them to the `_chartutil_` functions. ### For more information Helm's security policy is spelled out in detail in our [SECURITY](https://github.com/helm/community/blob/master/SECURITY.md) document. ### Credits Disclosed by Ada Logics in a fuzzing audit sponsored by CNCF.
