njs through 0.7.1, used in NGINX, was discovered to contain a control flow hijack caused by a Type Confusion vulnerability in njs_promise_perform_then().
njs through 0.4.3, used in NGINX, allows control-flow hijack in njs_value_property in njs_value.c. NOTE: the vendor considers the issue to be "fluff" in the NGINX use case because there is no remote attack surface.
