Amazon Linux 2023: CVE-2024-47220: Important priority package update for ruby3.2

An issue was discovered in the WEBrick toolkit through 1.8.1 for Ruby. It allows HTTP request smuggling by providing both a Content-Length header and a Transfer-Encoding header, e.g., "GET /admin HTTP/1.1\r\n" inside of a "POST /user HTTP/1.1\r\n" request. NOTE: the supplier's position is "Webrick should not be used in production."
A flaw was found in the webrick toolkit. This issue occurs because the server incorrectly handles requests with both Content-Length and Transfer-Encoding headers. This can allow an attacker to sneak in an extra request such as GET /admin after the normal request POST /user. As a result, unauthorized users can access restricted areas like /admin by POST /user.
