*) SECURITY: CVE-2009-3555 (cve.mitre.org) 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. [Joe Orton, and with thanks to the OpenSSL Team]
*) SECURITY: CVE-2009-3555 (cve.mitre.org) mod_ssl: A partial fix for the TLS renegotiation prefix injection attack by rejecting 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.

*) SECURITY: CVE-2010-0408 (cve.mitre.org) mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent when request headers indicate a request body is incoming; not a case of HTTP_INTERNAL_SERVER_ERROR. [Niku Toivola niku.toivola sulake.com ]
*) SECURITY: CVE-2010-0425 (cve.mitre.org) mod_isapi: Do not unload an isapi .dll module until the request processing is completed, avoiding orphaned callback pointers. [Brett Gervasoni brettg senseofsecurity.com , Jeff Trawick]
*) SECURITY: CVE-2010-0434 (cve.mitre.org) 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. PR 48359 [Jake Scott, William Rowe, Ruediger Pluem]
*) mod_reqtimeout: New module to set timeouts and minimum data rates for receiving requests from the client. [Stefan Fritsch]
*) mod_proxy_ajp: Really regard the operation a success, when the client aborted the connection. In addition adjust the log message if the client aborted the connection. [Ruediger Pluem]
*) mod_negotiation: Preserve query string over multiviews negotiation. This buglet was fixed for type maps in 2.2.6, but the same issue affected multiviews and was overlooked. PR 33112 [Joergen Thomsen apache jth.net ]
*) mod_cache: Introduce the thundering herd lock, a mechanism to keep the flood of requests at bay that strike a backend webserver as a cached entity goes stale. [Graham Leggett]
*) mod_proxy_http: Make sure that when an ErrorDocument is served from a reverse proxied URL, that the subrequest respects the status of the original request. This brings the behaviour of proxy_handler in line with default_handler. PR 47106. [Graham Leggett]
*) mod_log_config: Add the R option to log the handler used within the request. [Christian Folini christian.folini netnea com ]
*) mod_include: Allow fine control over the removal of Last-Modified and ETag headers within the INCLUDES filter, making it possible to cache responses if desired. Fix the default html' target='_blank'>value of the SSIAccessEnable directive. [Graham Leggett]
*) mod_ssl: Fix a potential I/O hang if a long list of trusted CAs is configured for client cert auth. PR 46952. [Joe Orton]
*) core: Fix potential memory leaks by making sure to not destroy bucket brigades that have been created by earlier filters. [Stefan Fritsch]

*) mod_ssl: When extracting certificate subject/issuer names to the SSL_*_DN_* variables, handle RDNs with duplicate tags by exporting multiple varialables with an _n integer suffix. PR 45875. [Joe Orton, Peter Sylvester peter.sylvester edelweb.fr ]
*) mod_authnz_ldap: Failures to map a username to a DN, or to check a user password now result in an informational level log entry instead of warning level. [Eric Covener]
*) core: Preserve Port information over internal redirects PR 35999 [Jonas Ringh jonas.ringh cixit.se ]
*) mod_ldap: If LDAPSharedCacheSize is too small, try harder to purge some cache entries and log a warning. Also increase the default LDAPSharedCacheSize to 500000. This is a more realistic size suitable for the default values of 1024 for LdapCacheEntries/LdapOpCacheEntries. PR 46749. [Stefan Fritsch]
