Apache 1.3.26 Released
The Apache Software Foundation and The Apache Server Project are pleased to announce the release of version 1.3.26 of the Apache HTTP Server. This Announcement notes the significant changes in 1.3.26. This newest version is primarily a security and bug-fix release designed to address security problems with chunked transfer encoding.
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 1.3.26 addresses and fixes the issues noted in CAN-2002-0392 (mitre.org) [CERT VU#944335] regarding a vulnerability in the handling of chunked transfer encoding. We would like to thank Mark Litchfield of ngssoftware.com for discovering and reporting the vulnerability.
We consider Apache 1.3.26 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. Users should also consider upgrading to Apache 2.0 as soon as all of the modules they need become available for 2.0.
Apache 1.3.26 is available for download from
Please see the CHANGES_1.3 file in the same directory for a full list of changes.
Binary distributions are available from
The source and binary distributions are also available via any of the mirrors listed at
As of Apache 1.3.17, Win32 binary distributions are now based on the Microsoft Installer (.MSI) technology. This change occurred in order to resolve the many problems WinME and Win2K users experienced with the older InstallShield-based installer.exe file. While development continues to make this new installation method more robust, questions should be directed at the news:comp.infosystems.www.servers.ms-windows newsgroup.
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.
For an overview of new features introduced after 1.2 please see
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 TPE 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 WIN32 USERS: Over the years, many users have come to trust Apache as a secure and stable server. It must be realized that the current Win32 code has not yet reached the levels of the Unix version, but is of acceptable quality. Win32 stability or security problems do not reflect on the Unix version.
Apache 1.3.26 Major changes
- Fix the security vulnerability noted in CAN-2002-0392 (mitre.org) regarding the handling of chunked transfer encoding.
The main new features in 1.3.26 (compared to 1.3.24) are:
- Add some popular types to the mime types magic file.
New features that relate to specific platforms:
- Unix: Added a '-F' flag which causes the supervisor process to no longer fork down and detach and instead stay attached to the tty - thus making live for automatic restart and exit checking code easier.
