Apache HTTP Server 1.3.34 Released
The Apache Software Foundation and The Apache HTTP Server Project
are
pleased to announce the release of version 1.3.34 of the Apache HTTP
Server ("Apache"). This Announcement notes the significant changes
in 1.3.34 as compared to 1.3.33. This Announcement1.3 document may
also be available in multiple languages at:
http://www.apache.org/dist/httpd/
This version of Apache is principally a bug and security fix
release.
A partial summary of the bug fixes is given at the end of this
document.
A full listing of changes can be found in the CHANGES file. Of
particular note is that 1.3.34 addresses and fixes 2 potential
security issues:
o If a request contains both Transfer-Encoding and
Content-Length headers, remove the Content-Length, mitigating
some
HTTP Request Splitting/Spoofing attacks.
o Added TraceEnable [on|off|extended] per-server directive to
alter
the behavior of the TRACE method.
We consider Apache 1.3.34 to be the best version of Apache 1.3
available
and we strongly recommend that users of older versions,
especially of
the 1.1.x and 1.2.x family, upgrade as soon as possible. No further
releases will be made in the 1.2.x family.
Apache 1.3.34 is available for download from:
http://httpd.apache.org/download.cgi
This service utilizes the network of mirrors listed at:
http://www.apache.org/mirrors/
Please consult the CHANGES_1.3 file for a full list of changes.
As of Apache 1.3.12 binary distributions contain all standard Apache
modules as shared objects (if supported by the platform) and include
full source code. Installation is easily done by executing the
included install script. See the README.bindist and INSTALL.bindist
files for a complete explanation. Please note that the binary
distributions are only provided for your convenience and current
distributions for specific platforms are not always available.
Win32
binary distributions are based on the Microsoft Installer (.MSI)
technology. While development continues to make this
installation method
more robust, questions should be directed to the
news:comp.infosystems.www.servers.ms-windows newsgroup.
For an overview of new features introduced after 1.2 please see
http://httpd.apache.org/docs/new_features_1_3.html
In general, Apache 1.3 offers several substantial improvements over
version 1.2, including better performance, reliability and a wider
range of supported platforms, including Windows NT and 2000 (which
fall under the "Win32" label), OS2, Netware, and TPF threaded
platforms.
Apache is the most popular web server in the known universe; over
half
of the servers on the Internet are running Apache or one of its
variants.
IMPORTANT NOTE FOR APACHE USERS: Apache 1.3 was designed for
Unix OS
variants. While the ports to non-Unix platforms (such as Win32,
Netware
or OS2) are of an acceptable quality, Apache 1.3 is not optimized
for
these platforms. Security, stability, or performance issues on
these
non-Unix ports do not generally apply to the Unix version, due to
software's Unix origin.
Apache 2.0 has been structured for multiple operating systems
from its
inception, by introducing the Apache Portability Library and MPM
modules.
Users on Unix and non-Unix platforms are strongly encouraged to
move up to
Apache 2.0 for better performance, stability and security on their
platforms. We consider Apache 2.0.55 to be the best available
version at
the time of this release. We offer Apache 1.3.34 as the best legacy
version of Apache 1.3 available, and strongly recommend that
users who
require compatibility with existing Apache 1.3 installations should
upgrade as soon as possible. Users should first consider
upgrading to
the current release of Apache 2 instead.
Apache 1.3.34 Major changes
Security vulnerabilities
* SECURITY: core: If a request contains both Transfer-Encoding and
Content-Length headers, remove the Content-Length, mitigating
some
HTTP Request Splitting/Spoofing attacks. This has no impact on
mod_proxy_http, yet affects any module which supports chunked
encoding yet fails to prefer T-E: chunked over the Content-
Length
purported value.
* Added TraceEnable [on|off|extended] per-server directive to
alter
the behavior of the TRACE method. This addresses a flaw in
proxy
conformance to RFC 2616 - previously the proxy server would
accept
a TRACE request body although the RFC prohibited it. The
default
remains 'TraceEnable on'.

Bugs fixed
The following noteworthy bugs were found in Apache 1.3.33 (or
earlier)
and have been fixed in Apache 1.3.34:
* hsregex: fix potential core dumping on 64 bit machines, such as
AMD64. PR 31858.
* mod_digest: Fix another nonce string calculation issue.
