Echo: tornado: security update to 6.4.2

high Tenable Cloud Security Plugin ID 463607

Description

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

 - Tornado is a Python web framework and asynchronous networking library. The algorithm used for parsing HTTP
 cookies in Tornado versions prior to 6.4.2 sometimes has quadratic complexity, leading to excessive CPU
 consumption when parsing maliciously-crafted cookie headers. This parsing occurs in the event loop thread
 and may block the processing of other requests. Version 6.4.2 fixes the issue. (CVE-2024-52804)

Solution

Update the tornado library and its related packages to version 6.4.2 or later.
