SCA: security update for github.com/phires/go-guerrilla (GHSA-c2c3-pqw5-5p7c)

medium Tenable Cloud Security Plugin ID 423606

Description

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

 - Go-Guerrilla SMTP Daemon is a lightweight SMTP server written in Go. Prior to 1.6.7, when ProxyOn is
 enabled, the PROXY command will be accepted multiple times, with later invocations overriding earlier
 ones. The proxy protocol only supports one initial PROXY header; anything after that is considered part of
 the exchange between client and server, so the client is free to send further PROXY commands with whatever
 data it pleases. go-guerrilla will treat these as coming from the reverse proxy, allowing a client to
 spoof its IP address. This vulnerability is fixed in 1.6.7. (CVE-2025-31135)
