Alpine: multiple py3-dask packages: security update to 2022.2.0-r0

critical Tenable Cloud Security Plugin ID 406637

Description

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

 - An issue was discovered in the Dask distributed package before 2021.10.0 for Python. Single machine Dask
 clusters started with dask.distributed.LocalCluster or dask.distributed.Client (which defaults to using
 LocalCluster) would mistakenly configure their respective Dask workers to listen on external interfaces
 (typically with a randomly selected high port) rather than only on localhost. A Dask cluster created using
 this method (when running on a machine that has an applicable port exposed) could be used by a
 sophisticated attacker to achieve remote code execution. (CVE-2021-42343)
