CVE-2022-41939 – Credential exposure when running third-party builders in knative/func

https://notcve.org/view.php?id=CVE-2022-41939

knative.dev/func is is a client library and CLI enabling the development and deployment of Kubernetes functions. Developers using a malicious or compromised third-party buildpack could expose their registry credentials or local docker socket to a malicious `lifecycle` container. This issues has been patched in PR #1442, and is part of release 1.8.1. This issue only affects users who are using function buildpacks from third-parties; pinning the builder image to a specific content-hash with a valid `lifecycle` image will also mitigate the attack. knative.dev/func es una librería cliente y CLI que permite el desarrollo y la implementación de funciones de Kubernetes. Los desarrolladores que utilizan un paquete de compilación de terceros malicioso o comprometido podrían exponer sus credenciales de registro o su conector acoplable local a un contenedor de "ciclo de vida" malicioso. • https://github.com/knative/func/blob/5ca77d38744d3481cc0b795f607c5859b19588fc/buildpacks/builder.go#L37-L41 https://github.com/knative/func/pull/1442 https://github.com/knative/func/releases/tag/knative-v1.8.1 https://github.com/knative/func/security/advisories/GHSA-5336-2g3f-9g3m • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
