llhttp allows HTTP Request Smuggling via Flawed Parsing of Transfer-Encoding

The llhttp parser in the http module in Node.js v17.x does not correctly parse and validate Transfer-Encoding headers and can lead to HTTP Request Smuggling (HRS).

Impacts:

• All versions of the nodejs 18.x, 16.x, and 14.x releases lines.
• llhttp v6.0.7 and llhttp v2.1.5 contains the fixes that were updated inside Node.js
