Apache httpd 2.4.58-1 with brotli compression library from Google, TLS 1.3, http2 (HTTP/2) support for Red Hat Enterprise Linux and CentOS 7/8, Alma Linux 8/9, Rocky Linux 8/9 added to repository. mod_http2 2.0.13 and mod_ssl are built dynamically against OpenSSL 3.0.11.
We build OpenSSL+QUIC 3.0.11 separately since v2.4.56-2, installing it separately to /lib64 with .so.81.3 suffix to ensure it won’t interfere with your system libraries. You can safely delete openssl111* packages. On EL8 and EL9 please enable httpd module:
dnf module enable httpd:codeit
Since 2.4.33 we added brotli compression library. Since 2.4.35 release we start building Apache httpd against OpenSSL 1.1.1*. Since 2.4.37 release TLS 1.3 final version (not to be confused with any draft versions) is supported and enabled by default. Please note that TLS 1.3 final version is supported in Chrome 70+ and Mozilla Firefox 63+. brotli support is already included in base RPM file. All you need is to add filters like
AddOutputFilterByType BROTLI_COMPRESS text/html text/plain text/xml text/css text/javascript application/javascript

Changes with Apache 2.4.58
*) SECURITY: CVE-2023-45802: Apache HTTP Server: HTTP/2 stream
memory not reclaimed right away on RST (cve.mitre.org)
When a HTTP/2 stream was reset (RST frame) by a client, there
was a time window were the request's memory resources were not
reclaimed immediately. Instead, de-allocation was deferred to
connection close. A client could send new requests and resets,
keeping the connection busy and open and causing the memory
footprint to keep on growing. On connection close, all resources
were reclaimed, but the process might run out of memory before
that.
This was found by the reporter during testing of CVE-2023-44487
(HTTP/2 Rapid Reset Exploit) with their own test client. During
"normal" HTTP/2 use, the probability to hit this bug is very
low. The kept memory would not become noticeable before the
connection closes or times out.
Users are recommended to upgrade to version 2.4.58, which fixes
the issue.

*) SECURITY: CVE-2023-43622: Apache HTTP Server: DoS in HTTP/2 with
initial windows size 0 (cve.mitre.org)
An attacker, opening a HTTP/2 connection with an initial window
size of 0, was able to block handling of that connection
indefinitely in Apache HTTP Server. This could be used to
exhaust worker resources in the server, similar to the well
known "slow loris" attack pattern.
This has been fixed in version 2.4.58, so that such connection
are terminated properly after the configured connection timeout.
This issue affects Apache HTTP Server: from 2.4.55 through
2.4.57.
Users are recommended to upgrade to version 2.4.58, which fixes
the issue.

(cve.mitre.org)
Out-of-bounds Read vulnerability in mod_macro of Apache HTTP
Server.This issue affects Apache HTTP Server: through 2.4.57.

*) mod_ssl: Silence info log message "SSL Library Error: error:0A000126:
SSL routines::unexpected eof while reading" when using
OpenSSL 3 by setting SSL_OP_IGNORE_UNEXPECTED_EOF if
available. [Rainer Jung]
*) mod_http2: improved early cleanup of streams.
[Stefan Eissing]
*) mod_proxy_http2: improved error handling on connection errors while
response is already underway.
[Stefan Eissing]
*) mod_http2: fixed a bug that could lead to a crash in main connection
output handling. This occured only when the last request on a HTTP/2
connection had been processed and the session decided to shut down.
This could lead to an attempt to send a final GOAWAY while the previous
write was still in progress. See PR 66646.
[Stefan Eissing]
*) mod_proxy_http2: fix `X-Forward-Host` header to carry the correct value.
Fixes PR66752.
[Stefan Eissing]
*) mod_http2: added support for bootstrapping WebSockets via HTTP/2, as
described in RFC 8441. A new directive 'H2WebSockets on|off' has been
added. The feature is by default not enabled.
As also discussed in the manual, this feature should work for setups
using "ProxyPass backend-url upgrade=websocket" without further changes.
Special server modules for WebSockets will have to be adapted,
most likely, as the handling if IO events is different with HTTP/2.
HTTP/2 WebSockets are supported on platforms with native pipes. This
excludes Windows.
[Stefan Eissing]
*) mod_rewrite: Fix a regression with both a trailing ? and [QSA].
in OCSP stapling. PR 66672. [Frank Meier , covener]
*) mod_http2: fixed a bug in flushing pending data on an already closed
connection that could lead to a busy loop, preventing the HTTP/2 session
to close down successfully. Fixed PR 66624.
[Stefan Eissing]
*) mod_http2: v2.0.15 with the following fixes and improvements
- New directive 'H2EarlyHint name value' to add headers to a response,
picked up already when a "103 Early Hints" response is sent. 'name' and
'value' must comply to the HTTP field restrictions.
This directive can be repeated several times and header fields of the
same names add. Sending a 'Link' header with 'preload' relation will
also cause a HTTP/2 PUSH if enabled and supported by the client.
- Fixed an issue where requests were not logged and accounted in a timely
fashion when the connection returns to "keepalive" handling, e.g. when
the request served was the last outstanding one.
This led to late appearance in access logs with wrong duration times
reported.
- Accurately report the bytes sent for a request in the '%O' Log format.
This addresses #203, a long outstanding issue where mod_h2 has reported
numbers over-eagerly from internal buffering and not what has actually
been placed on the connection.
The numbers are now the same with and without H2CopyFiles enabled.
[Stefan Eissing]
*) mod_proxy_http2: fix retry handling to not leak temporary errors.
On detecting that that an existing connection was shutdown by the other
side, a 503 response leaked even though the request was retried on a
fresh connection.
[Stefan Eissing]
*) mod_rewrite: Add server directory to include path as mod_rewrite requires
test_char.h. PR 66571 [Valeria Petrov ]
*) mod_http2: new directive `H2ProxyRequests on|off` to enable handling
of HTTP/2 requests in a forward proxy configuration.
General forward proxying is enabled via `ProxyRequests`. If the
HTTP/2 protocol is also enabled for such a server/host, this new
directive is needed in addition.
[Stefan Eissing]
*) core: Updated conf/mime.types:
- .js moved from 'application/javascript' to 'text/javascript'
- .mjs was added as 'text/javascript'
- add .opus ('audio/ogg')
- add 'application/vnd.geogebra.slides'
- add WebAssembly MIME types and extension

*) mod_proxy_http2: fixed using the wrong "bucket_alloc" from the backend
connection when sending data on the frontend one. This caused crashes
or infinite loops in rare situations.
*) mod_proxy_http2: fixed a bug in retry/response handling that could lead
to wrong status codes or HTTP messages send at the end of response bodies
exceeding the announced content-length.
*) mod_proxy_http2: fix retry handling to not leak temporary errors.
On detecting that that an existing connection was shutdown by the other
side, a 503 response leaked even though the request was retried on a
fresh connection.
*) mod_http2: fixed a bug that did cleanup of consumed and pending buckets in
the wrong order when a bucket_beam was destroyed.
[Stefan Eissing]
*) mod_http2: avoid double chunked-encoding on internal redirects.
PR 66597 [Yann Ylavic, Stefan Eissing]
*) mod_http2: Fix reporting of `Total Accesses` in server-status to not count
HTTP/2 requests twice. Fixes PR 66801.
[Stefan Eissing]
*) mod_ssl: Fix handling of Certificate Revoked messages
in OCSP stapling. PR 66626. []
*) mod_http2: fixed a bug in handling of stream timeouts.
[Stefan Eissing]
*) mod_tls: updating to rustls-ffi version 0.9.2 or higher.
Checking in configure for proper version installed. Code
fixes for changed clienthello member name.
[Stefan Eissing]
*) mod_md:
- New directive `MDMatchNames all|servernames` to allow more control over how
MDomains are matched to VirtualHosts.
- New directive `MDChallengeDns01Version`. Setting this to `2` will provide
the command also with the challenge value on `teardown` invocation. In version
1, the default, only the `setup` invocation gets this parameter.
Refs #312. Thanks to @domrim for the idea.
- For Managed Domain in "manual" mode, the checks if all used ServerName and
ServerAlias are part of the MDomain now reports a warning instead of an error
(AH10040) when not all names are present.
- MDChallengeDns01 can now be configured for individual domains.
Using PR from JГ©rГґme Billiras (@bilhackmac) and adding test case and fixing proper working
- Fixed a bug found by JГ©rГґme Billiras (@bilhackmac) that caused the challenge
teardown not being invoked as it should.
*) mod_ldap: Avoid performance overhead of APR-util rebind cache for
OpenLDAP 2.2+. PR 64414. [Joe Orton]
*) mod_http2: new directive 'H2MaxDataFrameLen n' to limit the maximum
amount of response body bytes put into a single HTTP/2 DATA frame.
Setting this to 0 places no limit (but the max size allowed by the
protocol is observed).
The module, by default, tries to use the maximum size possible, which is
somewhat around 16KB. This sets the maximum. When less response data is
available, smaller frames will be sent.
*) mod_md: fixed passing of the server environment variables to programs
started via MDMessageCmd and MDChallengeDns01 on *nix system.
See .
[Stefan Eissing]
*) mod_dav: Add DavBasePath directive to configure the repository root
path. PR 35077. [Joe Orton]
*) mod_alias: Add AliasPreservePath directive to map the full
path after the alias in a location. [Graham Leggett]
*) mod_alias: Add RedirectRelative to allow relative redirect targets to be
issued as-is. [Eric Covener, Graham Leggett]
*) core: Add formats %{z} and %{strftime-format} to ErrorLogFormat, and make
sure that if the format is configured early enough it applies to every log
line. PR 62161. [Yann Ylavic]
*) mod_deflate: Add DeflateAlterETag to control how the ETag
is modified. The 'NoChange' parameter mimics 2.2.x behavior.
PR 45023, PR 39727. [Eric Covener]
*) core: Optimize send_brigade_nonblocking(). [Yann Ylavic, Christophe Jaillet]
*) mod_status: Remove duplicate keys "BusyWorkers" and "IdleWorkers".
Resolve inconsistency between the previous two occurrences by
counting workers in state SERVER_GRACEFUL no longer as busy,
but instead in a new counter "GracefulWorkers" (or on HTML
view as "workers gracefully restarting"). Also add the graceful
counter as a new column to the existing HTML per process table
for async MPMs. PR 63300. [Rainer Jung]
