SCA: security update for dnspython, eventlet (GHSA-3rq5-2g8h-59hc)

high Tenable Cloud Security Plugin ID 409686

Description

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

 - eventlet before 0.35.2, as used in dnspython before 2.6.0, allows remote attackers to interfere with DNS
 name resolution by quickly sending an invalid packet from the expected IP address and source port, aka a
 "TuDoor" attack. In other words, dnspython does not have the preferred behavior in which the DNS name
 resolution algorithm would proceed, within the full time window, in order to wait for a valid packet.
 NOTE: dnspython 2.6.0 is unusable for a different reason that was addressed in 2.6.1. (CVE-2023-29483)
