Anyone running Win9x/ME should likely hold off on this for a bit.

It's non-functional at the moment. Of course, so is Win9x/ME, but that's
not the point. See:

Subject: [ANNOUNCE] Apache 2.0.44 Released
Date: Tue, 21 Jan 2003 00:26:38 +0100
From: Sander Striker <strikerapache.org>
To: <announcehttpd.apache.org>

The Apache Software Foundation and The Apache HTTP Server Project are
pleased to announce the seventh public release of the Apache 2.0
HTTP Server. This Announcement notes the significant changes in
2.0.44 as compared to 2.0.43.

This version of Apache is principally a security and bug fix release.
A summary of the bug fixes is given at the end of this document.
Of particular note is that 2.0.44 addresses three security
vulnerabilities affecting the Windows platform.

VU#979793 Versions of Windows 9x and Me could be crashed by a malicious
request to Apache that contains a MS-DOS device name. This is a known
security issues in Microsoft Windows for a which a fix is available:
http://www.microsoft.com/technet/Security/Bulletin/ms00-017.asp
Apache 2.0.44 has also been patched to correctly filter MS-DOS device
names preventing the crash even if the Microsoft update is not applied
(cve.mitre.org: CAN-2003-0016 [1]).

VU#825177 As a consequence of VU#979793, a remote attacker can
run arbitrary code on a server running Apache under Windows 9x and Me
by sending a carefully crafted POST request containing a MS-DOS device
name (cve.mitre.org: CAN-2003-0016 [1]).

On Windows platforms Apache could be forced to serve unexpected files
by appending illegal characters such as '<' to the request URL
(cve.mitre.org: CAN-2003-0017 [2]).

The Apache Software Foundation would like to thank Matthew Murphy and
Lionel Brits for the responsible reporting of these issues.

The 2.0.44 release marks a change in the Apache release process and a new
level of stability in the 2.0 series. Beginning with this release, we
will make every effort to retain forward compatibility in the
configuration and module API, so that upgrading along the 2.0 series
should be much easier. This compatibility extends backwards to 2.0.42, so
users of that version or later should be able to upgrade without changing
configurations or updating DSO modules. (Users of earlier releases will
need to recompile all modules in order to upgrade to 2.0.44.)

We consider this release to be the best version of Apache available
and encourage users of all prior versions to upgrade.

Apache 2.0.44 is available for download from

     http://httpd.apache.org/download.cgi

Please see the CHANGES_2.0 file, linked from the above page, for
a full list of changes.

Apache 2.0 offers numerous enhancements, improvements, and performance
boosts over the 1.3 codebase. For an overview of new features introduced
after 1.3 please see

     http://httpd.apache.org/docs-2.0/new_features_2_0.html

When upgrading or installing this version of Apache, please keep
in mind the following:

If you intend to use Apache with one of the threaded MPMs, you must
ensure that the modules (and the libraries they depend on) that you
will be using are thread-safe. Please contact the vendors of these
modules to obtain this information.

                    Apache 2.0.44 Major changes

Security vulnerabilities closed since Apache 2.0.43

  *) Fixed the security vulnerability noted in VU#979793: Apache vulnerable
     to DoS via request for MS-DOS device on Windows 9x and Me.

  *) Fixed the security vulnerability noted in VU#825177: Apache allows
     arbitrary code execution via crafted POST request containing MS-DOS
     device name on Windows 9x and Me.

  *) Fix CAN-2002-0017: On Windows platforms Apache could be forced to serve
     unexpected files by appending illegal characters such as '<' to the
     request URL.

Bugs fixed and features added since Apache 2.0.43

  *) mod_autoindex: Bring forward the IndexOptions IgnoreCase option
     from Apache 1.3. PR 14276
     [David Shane Holden <dpejeshyahoo.com>, William Rowe]

  *) mod_mime: Workaround to prevent a segfault if r->filename=NULL
     [Brian Pane]

  *) Reorder the definitions for mod_ldap and mod_auth_ldap within
     config.m4 to make sure the parent mod_ldap is defined first.
     This ensures that mod_ldap comes before mod_auth_ldap in the
     httpd.conf file, which is necessary for mod_auth_ldap to load.
     PR 14256 [Graham Leggett]

  *) Fix the building of cgi command lines when the query string
     contains '='. PR 13914 [Ville Skyttä <ville.skyttaiki.fi>,
     Jeff Trawick]

  *) Rename CacheMaxStreamingBuffer to MCacheMaxStreamingBuffer. Move
     implementation of MCacheMaxStreamingBuffer from mod_cache to
     mod_mem_cache. MCacheMaxStreamingBuffer now defaults to the
     lesser of 100,000 bytes or MCacheMaxCacheObjectSize. This should
     eliminate the need for explicitly coding MCacheMaxStreamingBuffer
     in most configurations. [Bill Stoddard]

  *) Replace APU_HAS_LDAPSSL_CLIENT_INIT with APU_HAS_LDAP_NETSCAPE_SSL
     as set by apr-util in util_ldap.c. This should allow mod_ldap
     to work with the Netscape/Mozilla LDAP library. [Øyvin Sømme
     <sommeoslo.westerngeco.slb.com>, Graham Leggett]

  *) Fix critical bug in new --enable-v4-mapped configure option
     implementation which broke IPv4 listening sockets on some
     systems. [hiroyuki hanai <hanaiimgsrc.co.jp>]

  *) mod_setenvif: Fix BrowserMatchNoCase support for non-regex
     patterns [André Malo <ndperlig.de>]

  *) Add version string to provider API. [Justin Erenkrantz]

  *) mod_negotiation: Set the appropriate mime response headers
     (Content-Type, charset, Content-Language and Content-Encoding)
     for negotated type-map "Body:" responses (such as the error
     pages.) [André Malo <ndperlig.de>]

  *) mod_log_config: Allow '%%' escaping in CustomLog format
     strings to insert a literal, single '%'.
     [André Malo <ndperlig.de>]

  *) mod_autoindex: AddDescription directives for directories
     now work as in Apache 1.3, where no trailing '/' is
     specified on the directory name. Previously, the trailing
     '/' *had* to be specified, which was incompatible with
     Apache 1.3. PR 7990 [Jeff Trawick]

  *) Fix for PR 14556. The expiry calculations in mod_cache were
     trying to perform "now + ((date - lastmod) * factor)" where
     date == lastmod resulting in "now + 0". The code now follows
     the else path (using the default expiration) if date is
     equal to lastmod. [rxarmstrike.com (Sergey), Paul J. Reder]

  *) Use AP_DECLARE in the debug versions of ap_strXXX in case the
     default calling convention is not the same as the one used by
     AP_DECLARE. [Juan Rivera <Juan.Riveracitrix.com>]

  *) mod_cache: Don't cache response header fields designated
     as hop-by-hop headers in HTTP/1.1 (RFC 2616 Section 13.5.1).
     [Estrade Matthieu <estrade-mifrance.com>, Brian Pane]

  *) mod_cgid: Handle environment variables containing newlines.
     PR 14550 [Piotr Czejkowski <apacheczarny.eu.org>, Jeff
     Trawick]

  *) Move mod_ext_filter out of experimental and into filters.
     [Jeff Trawick]

  *) Fixed a memory leak in mod_deflate with dynamic content.
     PR 14321 [Ken Franken <kfrankendecisionmark.com>]

  *) Add --[enable|disable]-v4-mapped configure option to control
     whether or not Apache expects to handle IPv4 connections
     on IPv6 listening sockets. Either setting will work on
     systems with the IPV6_V6ONLY socket option. --enable-v4-mapped
     must be used on systems that always allow IPv4 connections on
     IPv6 listening sockets. PR 14037 (Bugzilla), PR 7492 (Gnats)
     [Jeff Trawick]

  *) This fixes a problem where the underlying cache code
     indicated that there was one more element on the cache
     than there actually was. This happened since element 0
     exists but is not used. This code allocates the correct
     number of useable elements and reports the number of
     actually used elements. The previous code only allowed
     MCacheMaxObjectCount-1 objects to be stored in the
     cache. [Paul J. Reder]

  *) mod_setenvif: Add SERVER_ADDR special keyword to allow
     envariable setting according to the server IP address
     which received the request. [Ken Coar]

  *) mod_cgid: Terminate CGI scripts when the client connection
     drops. PR 8388 [Jeff Trawick]

  *) Rearrange OpenSSL engine initialization to support RAND
     redirection on crypto accelerator.
     [Frederic DONNAT <frederic.donnatzencod.com>]

  *) Always emit Vary header if mod_deflate is involved in the
     request. [Andre Malo <ndperlig.de>]

  *) mod_isapi: Stop unsetting the 'empty' query string result with
     a NULL argument in ecb->lpszQueryString, eliminating segfaults
     for some ISAPI modules. PR 14399
     [Detlev Vendt <detlev.vendtbrillit.de>]

  *) mod_isapi: Fix an issue where the HSE_REQ_DONE_WITH_SESSION
     notification is received before the HttpExtensionProc() returns
     HSE_STATUS_PENDING. This only affected isapi .dll's configured
     with the ISAPIFakeAsync on directive. PR 11918
     [John DeSetto <jdesettoradiantsystems.com>, William Rowe]

  *) mod_isapi: Fix the issue where all results from mod_isapi would
     run through the core die handler resulting in invalid responses
     or access log entries. PR 10216 [William Rowe]

  *) Improves the user friendliness of the CacheRoot processing
     over my last pass. This version avoids the pool allocations
     but doesn't avoid all of the runtime checks. It no longer
     terminates during post-config processing. An error is logged
     once per worker, indicating that the CacheRoot needs to be set.
     [Paul J. Reder]

  *) Fix a bug where we keep files open until the end of a
     keepalive connection, which can result in:
     (24)Too many open files: file permissions deny server access
     especially on threaded servers. [Greg Ames, Jeff Trawick]

  *) Fix a bug in which mod_proxy sent an invalid Content-Length
     when a proxied URL was invoked as a server-side include within
     a page generated in response to a form POST. [Brian Pane]

  *) Added code to process min and max file size directives and to
     init the expirychk flag in mod_disk_cache. Added a clarifying
     comment to cache_util. [Paul J. Reder]

  *) The value emitted by ServerSignature now mimics the Server HTTP
     header as controlled by ServerTokens. [Francis Daly <devadaoine.org>]

  *) Gracefully handly retry situations in the SSL input filter,
     by following the SSL libraries' retry semantics.
     [William Rowe]

  *) Terminate CGI scripts when the client connection drops. This
     fix only applies to some normal paths in mod_cgi. mod_cgid
     is still busted. PR 8388 [Jeff Trawick]

  *) Fix a bug where 416 "Range not satisfiable" was being
     returned for content that should have been redirected.
     [Greg Ames]

  *) Fix memory leak in mod_ssl from internal SSL library allocations
     within SSL_get_peer_certificate and X509_get_pubkey.
     [Zvi Har'El <rlmath.technion.ac.il>
      Madhusudan Mathihalli <madhusudan_mathihallihp.com>].

  *) mod_ssl uses free() inappropriately in several places, to free
     memory which has been previously allocated inside OpenSSL.
     Such memory should be freed with OPENSSL_free(), not with free().
     [Nadav Har'El <nyhmath.technion.ac.il>,
      Madhusudan Mathihalli <madhusudan_mathihallihp.com>].

  *) Emit a message to the error log when we return 404 because
     the URI contained '%2f'. (This was previously nastily silent
     and difficult to debug.) [Ken Coar]

  *) Fix streaming output from an nph- CGI script. CGI:IRC now
     works. PR 8482 [Jeff Trawick]

  *) More accurate logging of bytes sent in mod_logio when
     the client terminates the connection before the response
     is completely sent [Bojan Smojver <bojanrexursive.com>]

  *) Fix some problems in the perchild MPM.
     [Jonas Eriksson <jonaswebkonsulterna.com>]

  *) Change the CacheRoot processing to check for a required
     value at config time. This saves a lot of wasted processing
     if the mod_disk_cache module is loaded but no CacheRoot
     was provided. This fix also adds code to log an error
     and avoid useless pallocs and procesing when the computed
     cache file name cannot be opened. This also updates the
      docs accordingly. [Paul J. Reder]

  *) Introduce the EnableSendfile directive, allowing users of NFS
     shares to disable sendfile mechanics when they either fail
     outright or provide intermitantly corrupted data. PR
     [William Rowe]

  *) Resolve the error "An operation was attempted on something
     that is not a socket. : winnt_accept: AcceptEx failed.
     Attempting to recover." for users of various firewall and
     anti-virus software on Windows. PR 8325 [William Rowe]

  *) Add the ProxyBadHeader directive, which gives the admin some
     control on how mod_proxy should handle bogus HTTP headers from
     proxied servers. This allows 2.0 to "emulate" 1.3's behavior if
     desired. [Jim Jagielski]

  *) Change the LDAP modules to export their symbols correctly
     during a Windows build. Add dsp files for Windows. Update
     README.ldap file for Windows build instructions.
     [Andre Schild <A.Schildaarboard.ch>]

  *) Performance improvements for the code that generates HTTP
     response headers [Brian Pane]

  *) Add -S as a synonym for -t -DDUMP_VHOSTS.
     [Thom May <thomplanetarytramp.net>]

  *) Fix a bug with dbm rewrite maps which caused the wrong value to
     be used when the key was not found in the dbm. PR 13204
     [Jeff Trawick]

  *) Fix a problem with streaming script output and mod_cgid.
     [Jeff Trawick]

  *) Add ap_register_provider/ap_lookup_provider API.
     [John K. Sterling <johnsterls.com>, Justin Erenkrantz]
