## Description

Balabit Syslog-NG 1.4.x before 1.4.15, and 1.5.x before 1.5.20, when using template filenames or output, does not properly track the size of a buffer when constant characters are encountered during macro expansion, which allows remote attackers to cause a denial of service and possibly execute arbitrary code.

## What to do

- Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory per the references below.
