I am running FreeRadius 3.0.12 on Ubuntu 14.04.5 LTS with
The Radius server is used mainly as AAA server for a bunch of Cisco WLCs with a few
hundred Cisco WLAN APs behind. We are doing EAP-TLS, the devices only have to present
their certificates. Additionally it is used for authentication of admin users on Cisco devices,
here we use the ntlm_auth module. But i think this is not relevant.
The server crashes now quite frequently, the error always looks like this:
Mar 16 22:44:03 server kernel: [2614480.407628] freeradius: segfault at 44 ip
00007f21f1317f55 sp 00007f21e4ae5828 error 4 in libssl.so.1.0.0[7f21f12dc000+55000]
So, this looks like the crash was related to libssl. in general EAP-TLS works fine, several
thousand authentications per day, but then freeradius crashes with the above error. Might
be some certificate which openssl 1.0.1f does not understand? Maybe this is a TLSv1.2
certificate? Or should this be already fixed?
