ZABBIX server zabbix_agentd denial of service
| zabbix-zabbixagentd-dos (41196) |  Low Risk |
Description:
ZABBIX server is vulnerable to a denial of service, caused by an implementation error in the vfs.file.cksum command in zabbix_agentd. By sending a specially-crafted request using multiple vfs.file.cksum commands to the TCP port 10050, a remote attacker connected to an authorized host could exploit this vulnerability to cause the agent to consume an overly large amount of CPU resources, forcing the system to hang.
Platforms Affected:
- ZABBIX, ZABBIX Server 1.4.4
