                   Apache HTTP Server 2.0.52 Released

   The Apache Software Foundation and the  The Apache HTTP Server Project are
   pleased to announce the release of version 2.0.52 of the Apache HTTP
   Server ("Apache").  This Announcement notes the significant changes
   in 2.0.52 as compared to 2.0.51. 

   This version of Apache is principally a bug fix release.  Of
   particular note is that 2.0.52 addresses one new security related
   flaw introduced in 2.0.51:

     Fix merging of the Satisfy directive, which was applied to
     the surrounding context and could allow access despite configured
     authentication.
     [http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0811]

   The Apache HTTP Server Project would like to thank Rici Lake for
   identification and a proposed fix of this flaw.

   This release is compatible with modules compiled for 2.0.42 and
   later versions.  We consider this release to be the best version of
   Apache available and encourage users of all prior versions to
   upgrade.

   Apache HTTP Server 2.0.52 is available for download from

     http://httpd.apache.org/download.cgi?update=200409150645

   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.
