* Fixed PDF XSS issue where a non-GET request for a PDF file would crash the
Apache httpd process. Discovered by Steve Grubb at Red Hat.
* Removed an invalid "Internal error: Issuing "%s" for unspecified error."
message that was logged when denying with nolog/noauditlog set and
causing the request to be audited.
* Fixed parsing multipart content with a missing part header name which
would crash Apache. Discovered by "Internet Security Auditors"
(isecauditors.com).
* Added ability to specify the config script directly using --with-apr
and --with-apu.
* Updated copyright year to 2009.
* Added macro expansion for append/prepend action.
* Fixed race condition in concurrent updates of persistent counters. Updates
are now atomic.
* Cleaned up build, adding an option for verbose configure output and making
the mlogc build more portable.
Use ./configure as one is now supplied
libmxl2 is no longer optional but curl is
Rename doc/eg dirs from ap-security to ap-modsecurity
* Allow for disabling request body limit checks in phase:1
* Now log XML parsing/validation warnings and errors to be in the debug log
at levels 3 and 4, respectivly.
* Transformation caching has been deprecated, and is now off by default. We
now advise against using transformation caching in production.
* Improve request body processing error messages.

27 Nov 2007 - 2.1.4
-------------------
* Updated included Core Ruleset to version 1.5 and noted in the docs that
XML support is required to use the rules without modification.
* Fixed an evasion FP, mistaking a multipart non-boundary for a boundary.
* Fixed multiple warnings on Solaris and/or 64bit builds.
* Do not process subrequests in phase 2-4, but do hand off the request data.
* Fixed a blocking FP in the multipart parser, which affected Safari.
11 Sep 2007 - 2.1.3
-------------------
* Updated multipart parsing code adding variables to allow checking
for various parsing issues (request body abnormalities).
* Allow mod_rpaf and mod_extract_forwarded2 to work before ModSecurity.
* Quiet some compiler warnings.
* Do not block internal ErrorDocument requests after blocking request.
* Added ability to compile without an external API (use -DNO_MODSEC_API).
27 Jul 2007 - 2.1.2
-------------------
* Cleaned up and clarified some documentation.
* Update included core rules to latest version (1.4.3).
* Enhanced ability to alert/audit failed requests.
* Do not trigger "pause" action for internal requests.
* Fixed issue with requests that use internal requests. These had the
potential to be intercepted incorrectly when other Apache httpd modules
that used internal requests were used with mod_security.
* Added Solaris and Cygwin to the list of platforms not supporting the hidden
visibility attribute.
* Fixed decoding full-width unicode in t:urlDecodeUni.
* Lessen some overhead of debugging messages and calculations.
* Do not try to intercept a request after a failed rule. This fixes the
issue associated with an "Internal Error: Asked to intercept request
but was_intercepted is zero" error message.
* Added SecAuditLog2 directive to allow redundent concurrent audit log
index files. This will allow sending audit data to two consoles, etc.
* Small performance improvement in memory management for rule execution.
-------------------
* Add the PCRE_DOLLAR_ENDONLY option when compiling regular expression
for the @rx operator and variables.
* Really set PCRE_DOTALL option when compiling the regular expression
for the @rx operator as the docs state.
* Fixed potential memory corruption when expanding macros.
* Fixed error when a collection was retrieved from storage in the same second
as creation by setting the rate to zero.
* Fixed ASCIIZ (NUL) parsing for application/x-www-form-urlencoded forms.
* Fixed the faulty REQUEST_FILENAME variable, which used to change
the internal Apache structures by mistake.
* Updates to quiet some compiler warnings.
* Fixed some casting issues for compiling on NetWare (patch from Guenter Knauf)
Fix a typo in options.mk
23 Feb 2006 - 2.1.0
-------------------
* Removed the "Connection reset by peer" message, which has nothing
to do with us. Actually the message was downgraded from ERROR to
NOTICE so it will still appear in the debug log.
* Removed the (harmless) message mentioning LAST_UPDATE_TIME missing.
* It was not possible to remove a rule placed in phase 4 using
SecRuleRemoveById or SecRuleRemoveByMsg. Fixed.
* Fixed a problem with incorrectly setting requestBodyProcessor using
the ctl action.
* Bundled Core Rules 2.1-1.3.2b4.
* Updates to the reference manual.
* Reversed the return values of @validateDTD and @validateSchema, to
make them consistent with other operators.
* Added a few helpful debug messages in the XML validation area.
* Updates to the reference manual.
* Fixed the validateByteRange operator.
* Default value for the status action is now 403 (as it was supposed to
be but it was effectively 500).
* Rule exceptions (removing using an ID range or an regular expression)
is now applied to the current context too. (Previously it only worked
on rules that are inherited from the parent context.)
* Fix of a bug with expired variables.
* Fixed regular expression variable selectors for many collections.
* Performance improvements - up to two times for real-life work loads!
* Memory consumption improvements (not measured but significant).
* The allow action did not work in phases 3 and 4. Fixed.
* Unlocked collections GLOBAL and RESOURCE.
* Added support for variable expansion in the msg action.
* New feature: It is now possible to make relative changes to the
audit log parts with the ctl action. For example: "ctl:auditLogParts=+E".
* New feature: "tag" action. To be used for event categorisation.
* XML parser was not reporting errors that occured at the end
of XML payload.
* Files were not extracted from request if SecUploadKeepFiles was
Off. Fixed.
* Regular expressions that are too long are truncated to 256
characters before used in error messages. (In order to keep
the error messages in the log at a reasonable size.)
* Fixed the sha1 transformation function.
* Fixed the skip action.
* Fixed REQUEST_PROTOCOL, REMOTE_USER, and AUTH_TYPE.
* SecRuleEngine did not work in child configuration contexts
(e.g. <Location>).
* Fixed base64Decode and base64Encode.
15 Nov 2006 - 2.0.4
-------------------
* Fixed the "deprecatevar" action.
* Decreasing variable values did not work.
* Made "nolog" do what it is supposed to do - cause a rule match to
not be logged. Also "nolog" now implies "noauditlog" but it's
possible to follow "nolog" with "auditlog" and have the match
not logged to the error log but logged to the auditlog. (Not
something that strikes me as useful but it's possible.)
* Relative paths given to SecDataDir will now be treated as relative
* Decreasing variable values did not work.
* Made "nolog" do what it is supposed to do - cause a rule match to
not be logged. Also "nolog" now implies "noauditlog" but it's
possible to follow "nolog" with "auditlog" and have the match
not logged to the error log but logged to the auditlog. (Not
something that strikes me as useful but it's possible.)
* Relative paths given to SecDataDir will now be treated as relative
to the Apache server root.
* Added checks to make sure only correct actions are specified in
SecDefaultAction (some actions are required, some don't make any
sense) and in rules that are not chain starters (same). This should
make the unhelpful "Internal Error: Failed to add rule to the ruleset"
message go away.
* Fixed the problem when "SecRuleInheritance Off" is used in a context
with no rules defined.
* Fixed a problem of lost input (request body) data on some redirections,
for example when mod_rewrite is used.
web applications (or a web application firewall). Operating as an Apache Web
server module or standalone, the purpose of ModSecurity is to increase web
application security, protecting web applications from known and unknown
attacks.
This is the 2.x branch of modsecurity and only supports Apache 2.x
