Steps to reproduce:
Before version 2.0.22 there was a patch for the library that fixes this problem:
--- lib/ipmi_lan.c.orig 2013-06-26 11:10:45.000000000 +0300
+++ lib/ipmi_lan.c 2013-06-26 11:12:21.000000000 +0300

}
session_id = ipmi_get_uint32(msg->data+4);
Since version 2.0.23 and above, the code has changed and the next patch is already in upstream:

1. Install IPMI emulator in docker: https://github.com/vapor-ware/ipmi-simulator
2. Add user with User or Operator role, to see help:
ipmitool -H X.X.X.X -U ADMIN -P ADMIN -I lanplus user
User Commands:
summary [<channel number>]
list [<channel number>]
set name <user id> <username>
set password <user id> [<password> <16|20>]
disable <user id>
enable <user id>
priv <user id> <privilege level> [<channel number>]
Privilege levels:
* 0x1 - Callback
* 0x2 - User
* 0x3 - Operator
* 0x4 - Administrator
* 0x5 - OEM Proprietary
* 0xF - No Access
3. Setup host with IPMI in Zabbix and get some error logs repeating:

Checked on CentOS 7.5/Oracle Linux 7.5 and Ubuntu 18.04.1.
Expected:
No errors, because latest data is actual and data is gathered.
