Description:
Milen Rangelov has discovered a vulnerability in ZABBIX, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to the improper implementation of the "vfs.file.cksum" command in "zabbix_agentd". This can be exploited to disable the processing of valid requests via multiple "vfs.file.cksum" commands, having e.g. "/dev/urandom" as a parameter, sent to the port on which "zabbix_agentd" is listening (port 10050/TCP by default).
Successful exploitation requires that the malicious requests are sent from an authorized host.
The vulnerability is confirmed in version 1.4.4. Other versions may also be affected.
