What is CVE-2024-42331?

The vulnerability arises within the src/libs/zbxembed/browser.c file, specifically in the method es_browser_ctor, which retrieves a heap pointer from the Duktape JavaScript engine. If this heap pointer is later freed by garbage collection, the browser_push_error method within the src/libs/zbxembed/browser_error.c file could encounter a use-after-free situation, leading to undefined behavior that may impact the overall stability and security of the application.
