Kamilio crashing after being hit by malicious SIP messages


Recommended Posts

IS anyone else facing same issue in kazoo cluster?

kazoo Kamilio  Module is crashing after being hit by  malicious SIP messages , which is causing kamailio to crash and dump core files.

root@d1k1 ~]# ls -lh /tmp
total 2.4G
-rw-------. 1 kamailio daemon 1.4G Sep  9 09:18 core.4419
-rw-------. 1 kamailio daemon 1.4G Sep  9 08:39 core.4422
-rw-------. 1 kamailio daemon 216M Sep  9 10:29 core.4426


Even a single malicious attempt is crashing module.


Dumps are being created, which ultimately fills disk space.

when one kamailio   module fails, other in cluster also fail  in matter of seconds.
