Description

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)

malicious input. No included modules pass untrusted data to these

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)
