Описание
Helm is a package manager for Charts for Kubernetes. Prior to version 3.18.5, it is possible to craft a JSON Schema file in a manner which could cause Helm to use all available memory and have an out of memory (OOM) termination. This issue has been resolved in Helm 3.18.5. A workaround involves ensuring all Helm charts that are being loaded into Helm do not have any reference of $ref pointing to /dev/zero.
A flaw was found in helm.sh/helm/v3. A maliciously crafted JSON Schema file can trigger excessive memory consumption during Helm Chart validation, leading to an out-of-memory (OOM) termination. A remote attacker, requiring user interaction to provide the crafted file, can trigger this condition. This issue results in an application level denial of service affecting the Helm process.
Меры по смягчению последствий
To mitigate this flaw, ensure all Helm charts do not have any reference of $ref pointing to /dev/zero.
