[SOLVED] Freeradius service not starting.

[bobbythomas]

Hi All,

I have just upgraded the firewall to 17.7 and then installed the Freeradius plugin. But I am unable to bring up the Freeradius service. I tried it through gui as well as through cli, it doesn't start. Any help is highly appreciated.

Thank you,
Regards,
Bobby Thomas

Looks like a vulnerability in LibreSSL is the root cause. Any fix available?

Can you switch to OpenSSL just for testing?

[bobbythomas]

Switched back to Openssl and it's now working.

Yes, it's now working after switching back to OpenSSL. Looks like there is some issue with LibreSSL.

This is a false-positive in FreeRADIUS:

https://en.wikipedia.org/wiki/LibreSSL#22_September_2016

It sees LibreSSL, but doesn't know they don't change their mocked OpenSSL version number.

As both libraries are safe, we could add this to the default config with a comment that LibreSSL has a false positive and thus isn't vulnerable?

security.allow_vulnerable_openssl = 'CVE-2016-6304'

The problem is that this might not be the only one it complains about...

So we are bumping LibreSSL from 2.4.5 to 2.5.5 with 17.7.1, which has a different method of "advertising" itself which seems to fix this in a local test.

I can't provide a simple test package because LibreSSL has a major version bump so it's not just the FreeRADIUS package that would have to be updated but quite a few.

But feeling lucky so marking this solved.

Thanks for the update Franco. Waiting for 17.7.1.
