[ANNOUNCEMENT] Apache HTTP Server 2.3.6-alpha Released

           Apache HTTP Server 2.3.6-alpha Released

The Apache Software Foundation and the Apache HTTP Server Project are
pleased to announce the release of version 2.3.6-alpha of the Apache HTTP
Server ("Apache").  This version of Apache is principally an alpha release
to test new technology and features that are incompatible or too large for
the stable 2.2.x branch. This alpha release should not be presumed to
be compatible with binaries built against any prior or future version.

Apache HTTP Server 2.3.6-alpha is available for download from:


Apache 2.3 offers numerous enhancements, improvements, and performance
boosts over the 2.2 codebase.  For an overview of new features
introduced since 2.3 please see:


Please see the CHANGES_2.3 file, linked from the download page, for a
full list of changes.

This release includes the Apache Portable Runtime (APR) version 1.4.2
and APR-Util version 1.3.9 in a separate -deps tarball.  The APR libraries
must be upgraded for all features of httpd to operate correctly.

This release builds on and extends the Apache 2.2 API.  Modules written
for Apache 2.2 will need to be recompiled in order to run with Apache
2.3, and require minimal or no source code changes.



nginx 0.8 before 0.8.40 and 0.7 before 0.7.66, when running on Windows, allows remote attackers to obtain source code or unparsed content of arbitrary files under the web document root by appending ::$DATA to the URI. (CVSS:5.0) (Last Update:2010-06-18)


nginx 0.8.36 allows remote attackers to cause a denial of service (crash) via certain encoded directory traversal sequences that trigger memory corruption, as demonstrated using the “%c0.%c0.” sequence. (CVSS:5.0) (Last Update:2010-06-15)

[advisory] httpd Timeout detection flaw (mod_proxy_http) CVE-2010-2068

Vulnerability; httpd Timeout detection flaw (mod_proxy_http) CVE-2010-2068

Classification; important


    A timeout detection flaw in the httpd mod_proxy_http module causes
    proxied response to be sent as the response to a different request,
    and potentially served to a different client, from the HTTP proxy
    pool worker pipeline.

    This may represent a confidential data revealing flaw.

    This affects only Netware, Windows or OS2 builds of httpd version
    2.2.9 through 2.2.15, 2.3.4-alpha and 2.3.5-alpha, when the proxy
    worker pools have been enabled.  Earlier 2.2, 2.0 and 1.3 releases
    were not affected.


    We would like to thank Loren Anderson for the thorough research
    and reporting of this flaw.


    Apply any one of the following mitigations to avert the possibility
    of confidential information disclosure.

    * Do not load mod_proxy_http.

    * Do not configure/enable any http proxy worker pools with ProxySet
      or ProxyPass optional arguments.

    * The straightforward workaround to disable mod_proxy_http's reuse
      of backend connection pipelines is to set the following global

        SetEnv proxy-nokeepalive 1

    * Replace mod_proxy_http.so with a patched version, for source code
      see http://www.apache.org/dist/httpd/patches/apply_to_2.2.15/ or
      http://www.apache.org/dist/httpd/patches/apply_to_2.3.5/ and for
      binaries see the http://www.apache.org/dist/httpd/binaries/ tree
      for win32 or netware, as appropriate.

    * Upgrade to Apache httpd 2.2.16 or higher, once released.  There
      is no tentative release date scheduled.

Update Released; 11th June 2010
