Descriptions

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.

En el archivo src/libs/zbxembed/browser.c, el método es_browser_ctor recupera un puntero de montón del motor JavaScript de Duktape. Este puntero de montón es utilizado posteriormente por el método browser_push_error en el archivo src/libs/zbxembed/browser_error.c. En esta etapa, puede producirse un error de use-after-free si el puntero de montón wd->browser se libera mediante la recolección de elementos no utilizados.
