Some HTTP/2 implementations are vulnerable to unconstrained internal, interval, integral data
buffering, potentially leading to a denial of service. The attacker opens
the HTTP/2 window so the peer can send without constraint, however, they
leave the TCP window closed so the peer cannot actually write (many of)
the bytes on the wire. The attacker then sends a stream of requests for
a large response object. Depending on how the servers queue the responses,
this can consume excess memory, CPU, or both. (CVE-2019-9517)

HTTP/2 (2.4.20 through 2.4.39) very early pushes, for example configured
with 'H2PushResource', could lead to an overwrite of memory in the pushing
request's pool, leading to crashes. The memory copied is that of the
configured push link header values, not data supplied by the client.
(CVE-2019-10081)

In Apache HTTP Server 2.4.18-2.4.39, using fuzzed network input, the http/2
session handling could be made to read memory after being freed, during
connection shutdown. (CVE-2019-10082)

In Apache HTTP Server 2.4.0-2.4.39, a limited cross-site scripting issue
was reported affecting the mod_proxy error page. An attacker could cause
the link on the error page to be malformed and instead point to a page of
their choice. This would only be exploitable where a server was set up
with proxying enabled but was misconfigured in such a way that the Proxy
Error page was displayed. (CVE-2019-10092)

In Apache HTTP Server 2.4.32-2.4.39, when mod_remoteip was configured to
use a trusted intermediary proxy server using the 'PROXY' protocol, a
specially crafted PROXY header could trigger a stack buffer overflow or
NULL pointer deference. This vulnerability could only be triggered by a
trusted proxy and not by untrusted HTTP clients. (CVE-2019-10097)

In Apache HTTP server 2.4.0 to 2.4.39, Redirects configured with
mod_rewrite that were intended to be self-referential might be fooled by
encoded newlines and redirect instead to an unexpected URL within
the request URL. (CVE-2019-10098)");
