|
||||
*) 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.

|
||||
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

*) 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.
|
||||

|
||||
|
||||
*) mod_rewrite: Fix a regression with both a trailing ? and [QSA].
|
||||
in OCSP stapling. PR 66672. [Frank Meier <frank.meier ergon.ch>, 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.
|
||||

|
||||
|
||||
*) 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 <valeria.petrov@spinetix.com>]
|
||||
|
||||
*) 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.

|
||||
|

|
||||
in OCSP stapling. PR 66626. [<gmoniker gmail.com>]
|
||||
|
||||
*) 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 Jérôme Billiras (@bilhackmac) and adding test case and fixing proper working
|
||||
- Fixed a bug found by Jérôme 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 <https://github.com/icing/mod_md/issues/319>.

|
||||

|
||||

|
||||

Resolve inconsistency between the previous two occurrences by
|

counting workers in state SERVER_GRACEFUL no longer as busy,
|
