Hi,
i'm searching here and along zabbix website without luck.
Anyone knows how do I have to proceed to report security vulnerabilities on zabbix?

Thanks.

I happened to come across a page on an unrelated google search, and it has details of a Denial of Service attack occurring on systems running Zabix, by sending malformed requests to port 10500. Is it true? If so, has this been addressed?
