Security fix for CVE-2022-38725

Summary

syslog-ng is an enhanced log daemon, supporting a wide range of input and

output methods: syslog, unstructured text, message queues, databases (SQL

and NoSQL alike) and more.

Key features:

* receive and send RFC3164 and RFC5424 style syslog messages

* work with any kind of unstructured data

* receive and send JSON formatted messages

* classify and structure logs with builtin parsers (csv-parser(),

db-parser(), ...)

* normalize, crunch and process logs as they flow through the system

* hand on messages for further processing using message queues (like

AMQP), files or databases (like PostgreSQL or MongoDB).
