CVE-2024-42331: Zabbix

Low severity, CVSS 3.3. EPSS: 0.3% chance of exploitation in the next 30 days.

In the src/libs/zbxembed/browser.c file, the es_browser_ctor method retrieves a heap pointer from the Duktape JavaScript engine. This heap pointer is subsequently utilized by the browser_push_error method in the src/libs/zbxembed/browser_error.c file. A use-after-free bug can occur at this stage if the wd->browser heap pointer is freed by garbage collection.

Affected products

• Zabbix Zabbix: from 7.0.0, before 7.0.4 (fixed in 7.0.4)
