Hi,

FWIW as no CVEs were to be found yet, I filed a CVE request for Postfix now.

Not sure if we need it for others like sendmail too, as that is also
referenced by the security researchers.
Looks like exim opened a bug on this yesterday too, no sign of CVE yet:
<https://bugs.exim.org/show_bug.cgi?id=3063>
CVEs are assigned now for:

- CVE-2023-51764 postfix
- CVE-2023-51765 sendmail
- CVE-2023-51766 exim

Ciao, Marcus
