The vulnerability is marked as low-risk since all standard modules do not pass external data to this function. However, it is theoretically possible that third-party modules could facilitate an attack.\n<li class=\"l\"> CVE-2021-36160 \u2014 out-of-bounds read in the mod_proxy_uwsgi module, leading to a crash.\n<li class=\"l\"> CVE-2021-34798 \u2014 dereferencing a null pointer, resulting in a process crash when handling specially crafted requests.        <\/li>\n<\/ul>\n<p>The most notable changes not related to security:   <\/p>\n<ul>\n<li class=\"l\"> There are quite a few internal changes in mod_ssl.

The logging of closed keys has been added, which can be used in Wireshark for analyzing encrypted traffic.\n<li class=\"l\"> In mod_proxy, the parsing of paths with unix sockets transmitted in the 'proxy:' URL has been accelerated.\n<li class=\"l\"> The capabilities of the mod_md module, used for automating the acquisition and maintenance of certificates using the ACME (Automatic Certificate Management Environment) protocol, have been expanded. Quoting of domains in  is now allowed, and support for tls-alpn-01 has been provided. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/domain\/\"   title=\"domain names\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"912\">domain names<\/a>A new StrictHostCheck parameter has been added, prohibiting the specification of unconfigured host names among the arguments in the 'allow' list.\n<li class=\"l\"> A new parameter, StrictHostCheck, has been added to prevent the inclusion of unconfigured host names in the 'allow' list arguments.    <\/ul>\n<p>Source: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=55809\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0440\u0435\u043b\u0438\u0437 HTTP-\u0441\u0435\u0440\u0432\u0435\u0440\u0430 Apache 2.4.49, \u0432 \u043a\u043e\u0442\u043e\u0440\u043e\u043c \u043f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u043b\u0435\u043d\u043e 27 \u0438\u0437\u043c\u0435\u043d\u0435\u043d\u0438\u0439 \u0438 \u0443\u0441\u0442\u0440\u0430\u043d\u0435\u043d\u043e 5 \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u0435\u0439: CVE-2021-33193 &#8212; \u043f\u043e\u0434\u0432\u0435\u0440\u0436\u0435\u043d\u043d\u043e\u0441\u0442\u044c mod_http2 \u043d\u043e\u0432\u043e\u043c\u0443 \u0432\u0430\u0440\u0438\u0430\u043d\u0442\u0443 \u0430\u0442\u0430\u043a\u0438 &#171;HTTP Request Smuggling&#187;, \u043f\u043e\u0437\u0432\u043e\u043b\u044f\u044e\u0449\u0435\u043c\u0443 \u0447\u0435\u0440\u0435\u0437 \u043e\u0442\u043f\u0440\u0430\u0432\u043a\u0443 \u0441\u043f\u0435\u0446\u0438\u0430\u043b\u044c\u043d\u043e \u043e\u0444\u043e\u0440\u043c\u043b\u0435\u043d\u043d\u044b\u0445 \u043a\u043b\u0438\u0435\u043d\u0442\u0441\u043a\u0438\u0445 \u0437\u0430\u043f\u0440\u043e\u0441\u043e\u0432 \u0432\u043a\u043b\u0438\u043d\u0438\u0432\u0430\u0442\u044c\u0441\u044f \u0432 \u0441\u043e\u0434\u0435\u0440\u0436\u0438\u043c\u043e\u0435 \u0437\u0430\u043f\u0440\u043e\u0441\u043e\u0432 \u0434\u0440\u0443\u0433\u0438\u0445 \u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u0442\u0435\u043b\u0435\u0439, \u043f\u0435\u0440\u0435\u0434\u0430\u0432\u0430\u0435\u043c\u044b\u0445 \u0447\u0435\u0440\u0435\u0437 mod_proxy (\u043d\u0430\u043f\u0440\u0438\u043c\u0435\u0440, \u043c\u043e\u0436\u043d\u043e \u0434\u043e\u0431\u0438\u0442\u044c\u0441\u044f \u043f\u043e\u0434\u0441\u0442\u0430\u043d\u043e\u0432\u043a\u0438 \u0432\u0440\u0435\u0434\u043e\u043d\u043e\u0441\u043d\u043e\u0433\u043e JavaScript-\u043a\u043e\u0434\u0430 \u0432 \u0441\u0435\u0430\u043d\u0441 \u0434\u0440\u0443\u0433\u043e\u0433\u043e \u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u0442\u0435\u043b\u044f \u0441\u0430\u0439\u0442\u0430).
