GHSA-67fx-wx78-jx33
No affected components available
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.
