GCVE-VVD-MAGEIA-2021-439

A crafted method sent through HTTP/2 will bypass validation and be forwarded by mod_proxy, which can lead to request splitting or cache poisoning. (CVE-2021-33193) Malformed requests may cause the server to dereference a NULL pointer. (CVE-2021-34798) A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and crash (DoS). (CVE-2021-36160) ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules pass untrusted data to these functions, but third-party / external modules may. (CVE-2021-39275) A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. (CVE-2021-40438)
