Zabbix < 1.6.6 Null Pointer Dereference DoS



The remote host is vulnerable to denial-of-service attack.


The remote host is running Zabbix, an IT monitoring service. The installed version of Zabbix is earlier than 1.6.6. Such versions are potentially affected by a Null Pointer Dereference vulnerability in the 'process_trap()' function of the 'zabbix_server/trapper/trapper.c' source file. An attacker can exploit this flaw to crash the affected service.


Upgrade to Zabbix 1.6.6 or later.
