SCA: security update for dockerspawner (GHSA-hfgr-h3vc-p6c2)

medium Tenable Cloud Security Plugin ID 415681

Description

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

 - dockerspawner is a tool to spawn JupyterHub single user servers in Docker containers. Users of JupyterHub
 deployments running DockerSpawner starting with 0.11.0 without specifying `DockerSpawner.allowed_images`
 configuration allow users to launch _any_ pullable docker image, instead of restricting to only the single
 configured image, as intended. This issue has been addressed in commit `3ba4b665b` which has been included
 in dockerspawner release version 13. Users are advised to upgrade. Users unable to upgrade should
 explicitly set `DockerSpawner.allowed_images` to a non-empty list containing only the default image will
 result in the intended default behavior. (CVE-2023-48311)
