Apache HTTP Server(简称Apache)是Apache软件基金会的一个开放源码的网页服务器,可以在大多数电脑操作系统中运行,由于其跨平台和安全性被广泛使用,是最流行的Web服务器端软件之一。它快速、可靠并且可通过简单的API扩充,将Perl/Python等解释器编译到服务器中。

4月1日,Apache基金会的Apache HTTP Server(HTTPD)发布了稳定版2.4.43,相较于去年8月份的上一个稳定版2.4.41增加了新特性(2.4.42),并修复了一些安全漏洞。

CHANGES_2.4.43:

Changes with Apache 2.4.43

*) SECURITY: CVE-2020-1934 (cve.mitre.org)

mod_proxy_ftp: Use of uninitialized value with malicious backend FTP

server. [Eric Covener]

*) SECURITY: CVE-2020-1927 (cve.mitre.org)

rewrite, core: Set PCRE_DOTALL flag by default to avoid unpredictable

matches and substitutions with encoded line break characters.

The fix for CVE-2019-10098 was not effective.  [Ruediger Pluem]

*) mod_ssl: Fix memory leak of OCSP stapling response. [Yann Ylavic]

Changes with Apache 2.4.42

*) mod_proxy_http: Fix the forwarding of requests with content body when a

balancer member is unavailable; the retry on the next member was issued

with an empty body (regression introduced in 2.4.41). PR63891.

[Yann Ylavic]

*) mod_http2: Fixes issue where mod_unique_id would generate non-unique request

identifier under load, see <https://github.com/icing/mod_h2/issues/195>.

[Michael Kaufmann, Stefan Eissing]

*) mod_proxy_hcheck: Allow healthcheck expressions to use %{Content-Type}.

PR64140. [Renier Velazco <renier.velazco upr.edu>]

*) mod_authz_groupfile: Drop AH01666 from loglevel "error" to "info".

PR64172.

*) mod_usertrack: Add CookieSameSite, CookieHTTPOnly, and CookieSecure

to allow customization of the usertrack cookie. PR64077.

[Prashant Keshvani <prashant2400 gmail.com>, Eric Covener]

*) mod_proxy_ajp: Add "secret" parameter to proxy workers to implement legacy

AJP13 authentication.  PR 53098. [Dmitry A. Bakshaev <dab1818 gmail com>]

*) mpm_event: avoid possible KeepAliveTimeout off by -100 ms.

[Eric Covener, Yann Ylavic]

*) Add a config layout for OpenWRT. [Graham Leggett]

*) Add support for cross compiling to apxs. If apxs is being executed from

somewhere other than its target location, add that prefix to includes and

library directories. Without this, apxs would fail to find config_vars.mk

and exit. [Graham Leggett]

*) mod_ssl: Disable client verification on ACME ALPN challenges. Fixes github

issue mod_md#172 (https://github.com/icing/mod_md/issues/172).

[Michael Kaufmann <mail michael-kaufmann.ch>, Stefan Eissing]

*) mod_ssl: use OPENSSL_init_ssl() to initialise OpenSSL on versions 1.1+.

[Graham Leggett]

*) mod_ssl: Support use of private keys and certificates from an

OpenSSL ENGINE via PKCS#11 URIs in SSLCertificateFile/KeyFile.

[Anderson Sasaki <ansasaki redhat.com>, Joe Orton]

*) mod_md:

- Prefer MDContactEmail directive to ServerAdmin for registration. New directive

thanks to Timothe Litt (@tlhackque).

- protocol check for pre-configured "tls-alpn-01" challenge has been improved. It will now

check all matching virtual hosts for protocol support. Thanks to @mkauf.

- Corrected a check when OCSP stapling was configured for hosts

where the responsible MDomain is not clear, by Michal Karm Babacek (@Karm).

- Softening the restrictions where mod_md configuration directives may appear. This should

allow for use in <If> and <Macro> sections. If all possible variations lead to the configuration

you wanted in the first place, is another matter.

[Michael Kaufmann <mail michael-kaufmann.ch>, Timothe Litt (@tlhackque),

Michal Karm Babacek (@Karm), Stefan Eissing (@icing)]

*) test: Added continuous testing with Travis CI.

This tests various scenarios on Ubuntu with the full test suite.

Architectures tested: AMD64, s390x, ppc64le, arm64

The tests pass successfully.

[Luca Toscano, Joe Orton, Mike Rumph, and others]

*) core: Be stricter in parsing of Transfer-Encoding headers.

[ZeddYu <zeddyu.lu gmail.com>, Eric Covener]

*) mod_ssl: negotiate the TLS protocol version per name based vhost

configuration, when linked with OpenSSL-1.1.1 or later. The base vhost's

SSLProtocol (from the first vhost declared on the IP:port) is now only

relevant if no SSLProtocol is declared for the vhost or globally,

otherwise the vhost or global value apply.  [Yann Ylavic]

*) mod_cgi, mod_cgid: Fix a memory leak in some error cases with large script

output.  PR 64096.  [Joe Orton]

*) config: Speed up graceful restarts by using pre-hashed command table. PR 64066.

[Giovanni Bechis <giovanni paclan.it>, Jim Jagielski]

*) mod_systemd: New module providing integration with systemd.  [Jan Kaluza]

*) mod_lua: Add r:headers_in_table, r:headers_out_table, r:err_headers_out_table,

r:notes_table, r:subprocess_env_table as read-only native table alternatives

that can be iterated over. [Eric Covener]

*) mod_http2: Fixed rare cases where a h2 worker could deadlock the main connection.

[Yann Ylavic, Stefan Eissing]

*) mod_lua: Accept nil assignments to the exposed tables (r.subprocess_env,

r.headers_out, etc) to remove the key from the table. PR63971.

[Eric Covener]

*) mod_http2: Fixed interaction with mod_reqtimeout. A loaded mod_http2 was disabling the

ssl handshake timeouts. Also, fixed a mistake of the last version that made `H2Direct`

always `on`, regardless of configuration. Found and reported by

<Armin.Abfalterer@united-security-providers.ch> and

<Marcial.Rion@united-security-providers.ch>. [Stefan Eissing]

*) mod_http2: Multiple field length violations in the same request no longer cause

several log entries to be written. [@mkauf]

*) mod_ssl: OCSP does not apply to proxy mode.  PR 63679.

[Lubos Uhliarik <luhliari redhat.com>, Yann Ylavic]

*) mod_proxy_html, mod_xml2enc: Fix build issues with macOS due to r1864469

[Jim Jagielski]

*) mod_authn_socache: Increase the maximum length of strings that can be cached by

the module from 100 to 256.  PR 62149 [<thorsten.meinl knime.com>]

*) mod_proxy: Fix crash by resolving pool concurrency problems. PR 63503

[Ruediger Pluem, Eric Covener]

*) core: On Windows, fix a start-up crash if <IfFile ...> is used with a path that is not

valid (For example, testing for a file on a flash drive that is not mounted)

[Christophe Jaillet]

*) mod_deflate, mod_brotli: honor "Accept-Encoding: foo;q=0" as per RFC 7231; which

means 'foo' is "not acceptable".  PR 58158 [Chistophe Jaillet]

*) mod_md v2.2.3:

- Configuring MDCAChallenges replaces any previous existing challenge configuration. It

had been additive before which was not the intended behaviour. [@mkauf]

- Fixing order of ACME challenges used when nothing else configured. Code now behaves as

documented for `MDCAChallenges`. Fixes #156. Thanks again to @mkauf for finding this.

- Fixing a potential, low memory null pointer dereference [thanks to @uhliarik].

- Fixing an incompatibility with a change in libcurl v7.66.0 that added unwanted

"transfer-encoding" to POST requests. This failed in directy communication with

Let's Encrypt boulder server. Thanks to @mkauf for finding and fixing. [Stefan Eissing]

*) mod_md: Adding the several new features.

The module offers an implementation of OCSP Stapling that can replace fully or

for a limited set of domains the existing one from mod_ssl. OCSP handling

is part of mod_md's monitoring and message notifications. If can be used

for sites that do not have ACME certificates.

The url for a CTLog Monitor can be configured. It is used in the server-status

to link to the external status page of a certicate.

The MDMessageCmd is called with argument "installed" when a new certificate

has been activated on server restart/reload. This allows for processing of

the new certificate, for example to applications that require it in different

locations or formats.

[Stefan Eissing]

*) mod_proxy_balancer: Fix case-sensitive referer check related to CSRF/XSS

protection. PR 63688. [Armin Abfalterer <a.abfalterer gmail.com>]
