SCA: security update for priority (GHSA-h3q4-6j7f-r24c)

high Tenable Self-Hosted Container Security Plugin ID 431819

Description

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

 - A HTTP/2 implementation built using any version of the Python priority library prior to version 1.2.0
 could be targeted by a malicious peer by having that peer assign priority information for every possible
 HTTP/2 stream ID. The priority tree would happily continue to store the priority information for each
 stream, and would therefore allocate unbounded amounts of memory. Attempting to actually use a tree like
 this would also cause extremely high CPU usage to maintain the tree. (CVE-2016-6580)
