Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

The JavaScript preprocessing (Duktape) engine on Zabbix server has a vulnerability where a limited administrator is able to read raw heap data potentially resulting in leaked data from other running preprocessors not available to said administrator.
