Description Michael Kaplan 2022-01-14 16:15:32 UTC

During Zabbix installation from RPM, DAC_OVERRIDE SELinux capability is in use to access PID files in [/var/run/zabbix] folder. In this case, Zabbix Proxy or Server processes can bypass file read, write and execute permissions check on the file system level
