- Update to 2.4.55:
*) SECURITY: CVE-2022-37436: Apache HTTP Server: mod_proxy prior to
2.4.55 allows a backend to trigger HTTP response splitting
(cve.mitre.org)
Prior to Apache HTTP Server 2.4.55, a malicious backend can
cause the response headers to be truncated early, resulting in
some headers being incorporated into the response body. If the
later headers have any security purpose, they will not be
interpreted by the client.

Possible request smuggling (cve.mitre.org)
Inconsistent Interpretation of HTTP Requests ('HTTP Request
Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server
allows an attacker to smuggle requests to the AJP server it
forwards requests to. This issue affects Apache HTTP Server
Apache HTTP Server 2.4 version 2.4.54 and prior versions.

*) SECURITY: CVE-2006-20001: mod_dav out of bounds read, or write
of zero byte (cve.mitre.org)
A carefully crafted If: request header can cause a memory read,
or write of a single zero byte, in a pool (heap) memory location
beyond the header value sent. This could cause the process to
crash.
This issue affects Apache HTTP Server 2.4.54 and earlier.

*) SECURITY: CVE-2022-31813: mod_proxy X-Forwarded-For dropped by
hop-by-hop mechanism (cve.mitre.org)
Apache HTTP Server 2.4.53 and earlier may not send the
X-Forwarded-* headers to the origin server based on client side
Connection header hop-by-hop mechanism.
This may be used to bypass IP based authentication on the origin
server/application.

*) SECURITY: CVE-2022-30522: mod_sed denial of service
(cve.mitre.org)
If Apache HTTP Server 2.4.53 is configured to do transformations
with mod_sed in contexts where the input to mod_sed may be very
large, mod_sed may make excessively large memory allocations and
trigger an abort.

*) core/mod_proxy/mod_ssl:
Adding `outgoing` flag to conn_rec, indicating a connection is
initiated by the server to somewhere, in contrast to incoming
connections from clients.
Adding 'ap_ssl_bind_outgoing()` function that marks a connection
as outgoing and is used by mod_proxy instead of the previous
optional function `ssl_engine_set`. This enables other SSL
module to secure proxy connections.
The optional functions `ssl_engine_set`, `ssl_engine_disable` and
`ssl_proxy_enable` are now provided by the core to have backward
compatibility with non-httpd modules that might use them. mod_ssl
itself no longer registers these functions, but keeps them in its
header for backward compatibility.
The core provided optional function wrap any registered function
like it was done for `ssl_is_ssl`.

*) core: Adding SSL related inquiry functions to the server API.
These function are always available, even when no module providing
SSL is loaded. They provide their own "shadowing" implementation for
the optional functions of similar name that mod_ssl and impersonators
of mod_ssl provide.
This enables loading of several SSL providing modules when all but
one of them registers itself into the new hooks. Two old-style SSL
modules will not work, as they replace the others optional functions
with their own.
Modules using the old-style optional functions will continue to work
as core supplies its own versions of those.
The following has been added so far:
- ap_ssl_conn_is_ssl() to query if a connection is using SSL.
- ap_ssl_var_lookup() to query SSL related variables for a
server/connection/request.
- Hooks for 'ssl_conn_is_ssl' and 'ssl_var_lookup' where modules
providing SSL can install their own value supplying functions.
- ap_ssl_add_cert_files() to enable other modules like mod_md to provide
certificate and keys for an SSL module like mod_ssl.
- ap_ssl_add_fallback_cert_files() to enable other modules like mod_md to
