+
+    *) Security: processing of a specially crafted mp4 file by the
+       ngx_http_mp4_module might cause a worker process crash, worker
+       process memory disclosure, or might have potential other impact
+       (CVE-2022-41741, CVE-2022-41742).

+    *) Безопасность: обработка специально созданного mp4-файла модулем
+       ngx_http_mp4_module могла приводить к падению рабочего процесса,
+       отправке клиенту части содержимого памяти рабочего процесса, а также
+       потенциально могла иметь другие последствия (CVE-2022-41741,
+       CVE-2022-41742).
