Apache HTTP Server 2.2.32 Released
January 13, 2017
The Apache Software Foundation and the Apache HTTP Server Project are
pleased to announce the release of version 2.2.32 of the Apache HTTP
Server ("Apache"). This version of Apache is principally a security
and bug fix maintenance release, and addresses these specific security
defects as well as other fixes;
Enforce HTTP request grammar corresponding to RFC7230 for request
lines and request headers, to prevent response splitting and cache
pollution by malicious clients or downstream proxies.
We consider the Apache HTTP Server 2.4 release to be the best version
of Apache available, and encourage users of 2.2 and all prior versions
to upgrade. This 2.2 maintenance release is offered for those unable
to upgrade at this time.
Please note that Apache Web Server Project will only provide maintenance
releases of the 2.2.x flavor through June of 2017, and will provide some
security patches beyond this date through at least December of 2017.
Minimal maintenance patches of 2.2.x are expected throughout this period,
and users are strongly encouraged to promptly complete their transitions
to the the 2.4.x flavor of httpd to benefit from a much larger assortment
of minor security and bug fixes as well as new features.
For further details, see:
Apache HTTP Server 2.4 and 2.2.32 are available for download from:
Please see the CHANGES_2.2 file, linked from the download page, for a
full list of changes. A condensed list, CHANGES_2.2.32 includes only
those changes introduced since the prior 2.2 release. A summary of all
of the security vulnerabilities addressed in this and earlier releases
This release includes the Apache Portable Runtime (APR) version 1.5.2
and APR Utility Library (APR-util) version 1.5.4, bundled with the tar
and zip distributions. The APR libraries libapr and libaprutil (and
on Win32, libapriconv version 1.2.1) must all be updated to ensure
binary compatibility and address many known security and platform bugs.
APR version 1.5 and APR-util version 1.5 represent minor version upgrades
from earlier httpd 2.2 source distributions.
Note this package also includes very stale and known-vulnerable versions
of the Expat [http://expat.sourceforge.net/] and PCRE [http://www.pcre.org/]
packages. Users are strongly encouraged to first install the most recent
versions of these components (of PCRE 8.x, not PCRE2 10.x at this time.)
This release builds on and extends the Apache 2.0 API and is superceeded
by the Apache 2.4 API. Modules written for Apache 2.0 or 2.4 will need
to be recompiled in order to run with Apache 2.2, and most will require
minimal or no source code changes.
When upgrading or installing this version of Apache, please bear in mind
that if you intend to use Apache with one of the threaded MPMs (other
than the Prefork MPM), you must ensure that any modules you will be
using (and the libraries they depend on) are thread-safe.
