Apache HTTP Server 2.0.64 Released
The Apache Software Foundation and the Apache HTTP Server Project are
pleased to announce the release of version 2.0.64 of the Apache HTTP
Server ("Apache"). This version of Apache is a bug and security fix
release, covering a number of issues addressed previously in stable
mod_dav: Fix Handling of requests without a path segment.
Fix a potential Denial-of-Service attack against mod_deflate or other
modules, by forcing the server to consume CPU time in compressing a
large file after a client disconnects.
mod_proxy_ftp: sanity check authn credentials.
mod_proxy_ftp: NULL pointer dereference on error paths.
mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
attack when compiled against OpenSSL version 0.9.8m or later. Introduces
the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
and offer unsafe legacy renegotiation with clients which do not yet
support the new secure renegotiation protocol, RFC 5746.
mod_ssl: A partial fix for the TLS renegotiation prefix injection
attack for OpenSSL versions prior to 0.9.8l; reject any client-initiated
renegotiations. Forcibly disable keepalive for the connection if there
is any buffered data readable. Any configuration which requires
renegotiation for per-directory/location access control is still
vulnerable, unless using openssl 0.9.8l or later.
Ensure each subrequest has a shallow copy of headers_in so that the
parent request headers are not corrupted. Elimiates a problematic
optimization in the case of no request body.
mod_proxy_http: Better handling of excessive interim responses
from origin server to prevent potential denial of service and high
mod_isapi: Do not unload an isapi .dll module until the request
processing is completed, avoiding orphaned callback pointers.
mod_proxy_ftp: Prevent XSS attacks when using wildcards in the path of
the FTP URL.
and includes security fixes of the APR and APR-util 0.9.19 dependencies;
Fix a denial of service attack against apr_brigade_split_line().
Fix two buffer over-read flaws in the bundled copy of expat which
could cause applications to crash while parsing specially-crafted
Fix overflow in rmm, where size alignment was taking place.

This release is compatible with modules compiled for 2.0.42 and later
versions. We consider this release to be the best version of the legacy
Apache 2.0 available, and encourage users of all prior versions to
upgrade to no less than this release. The Apache HTTP Project
developers strongly encourages all users to migrate to Apache 2.2, as
only limited and less frequent maintenance is performed on this legacy
This release includes the Apache Portable Runtime library suite release
version 0.9.19, bundled with the tar and zip distributions. These
libraries; libapr, libaprutil, and on Win32, libapriconv must all be
updated to ensure binary compatibility and address many known platform
