SCA: security update for waitress (GHSA-4ppp-gpcr-7qf6)

high Tenable Cloud Security Plugin ID 423130

Description

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

 - Waitress through version 1.3.1 allows request smuggling by sending the Content-Length header twice.
 Waitress would header fold a double Content-Length header and due to being unable to cast the now comma
 separated value to an integer would set the Content-Length to 0 internally. If two Content-Length headers
 are sent in a single request, Waitress would treat the request as having no body, thereby treating the
 body of the request as a new request in HTTP pipelining. This issue is fixed in Waitress 1.4.0.
