Description Sam Fowler 2021-06-08 05:43:41 UTC 
An information disclosure vulnerability was found in buildah, when using `buildah bud` with chroot isolation. Dockerfile RUN commands executed during rootless `buildah bud` execution can read environment variables from the host, which may include sensitive information, such as container registry credentials.
