SCA: security update for protocol-http1 (GHSA-6jwc-qr2q-7xwj)

medium Tenable Self-Hosted Container Security Plugin ID 411509

Description

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

 - protocol-http1 provides a low-level implementation of the HTTP/1 protocol. RFC 9112 Section 7.1 defined
 the format of chunk size, chunk data and chunk extension. The value of Content-Length header should be a
 string of 0-9 digits, the chunk size should be a string of hex digits and should split from chunk data
 using CRLF, and the chunk extension shouldn't contain any invisible character. However, Falcon has
 following behaviors while disobey the corresponding RFCs: accepting Content-Length header values that have
 `+` prefix, accepting Content-Length header values that written in hexadecimal with `0x` prefix, accepting
 `0x` and `+` prefixed chunk size, and accepting LF in chunk extension. This behavior can lead to desync
 when forwarding through multiple HTTP parsers, potentially results in HTTP request smuggling and firewall
 bypassing. This issue is fixed in `protocol-http1` v0.15.1. There are no known workarounds.
 (CVE-2023-38697)
