A "Strange" Hack: Fake?

Browsing the internet I found a "strange" hack announcement: is this a fake or am I too noob to understand?

https://bitcointalk.org/index.php?topic=999560.msg11287458#msg11287458

He says he exploits "Exim smtpd 4.85"

The exploit code he posts start with this line:

#Exim 4.85 (RedHat/Centos/Debian) Remote Root Exploit by Kingcope

But it's identical to this exploit: https://www.exploit-db.com/exploits/15725/, that starts with this line:

#Exim 4.63 (RedHat/Centos/Debian) Remote Root Exploit by Kingcope

This exploits refers to this CVE: CVE-2010-4344 (https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2010-4344), that seems to affect only versions before 4.70 (so 4.85 should not be included).

So, it's this hack a fake? Or am I missing something?
