Hi,

The following vulnerability was published for rsyslog. Filling for now
as grave, but we might downgrade. Probably affected configurations are
not that common if I understood correctly, the advisory has some
comments about it as well[1].

| Potential heap buffer overflow in TCP syslog server (receiver)
| components

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Yeah, I think this feature is obscure enough (and not enabled by
