SCA: security update for binderhub (GHSA-9jjr-qqfp-ppwx)

critical Tenable Self-Hosted Container Security Plugin ID 413336

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - BinderHub is a kubernetes-based cloud service that allows users to share reproducible interactive
 computing environments from code repositories. In affected versions a remote code execution vulnerability
 has been identified in BinderHub, where providing BinderHub with maliciously crafted input could execute
 code in the BinderHub context, with the potential to egress credentials of the BinderHub deployment,
 including JupyterHub API tokens, kubernetes service accounts, and docker registry credentials. This may
 provide the ability to manipulate images and other user created pods in the deployment, with the potential
 to escalate to the host depending on the underlying kubernetes configuration. Users are advised to update
 to version 0.2.0-n653. If users are unable to update they may disable the git repo provider by specifying
 the `BinderHub.repo_providers` as a workaround. (CVE-2021-39159)
