5Release 2.4.7 Fri March 4 2022
6        Bug fixes:
7       #572 #577  Relax fix to CVE-2022-25236 (introduced with release 2.4.5)
8                    with regard to all valid URI characters (RFC 3986),
9                    i.e. the following set (excluding whitespace):
10                    ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz
11                    0123456789 % -._~ :/?#[]@ !$&'()*+,;=

14  #555 #570 #581  CMake|Windows: Store Expat version in the DLL
15            #577  Document consequences of namespace separator choices not just
16                    in doc/reference.html but also in header <expat.h>
17            #577  Document Expat's lack of validation of namespace URIs against
18                    RFC 3986, and that the XML 1.0r4 specification doesn't
19                    require Expat to validate namespace URIs, and that Expat
20                    may do more in that regard in future releases.
21                    If you find need for strict RFC 3986 URI validation on
22                    application level today, https://uriparser.github.io/ may
23                    be of interest.
24            #579  Fix documentation of XML_EndDoctypeDeclHandler in <expat.h>
25            #575  Document that a call to XML_FreeContentModel can be done at
26                    a later time from outside the element declaration handler
27            #574  Make hardcoded namespace URIs easier to find in code
28            #573  Update documentation on use of XML_POOR_ENTOPY on Solaris
29       #569 #571  tests: Resolve use of macros NAN and INFINITY for GNU G++
30                    4.8.2 on Solaris.

42                    in release 2.4.5 that affects applications that (1)
43                    call function XML_SetElementDeclHandler and (2) are
44                    parsing XML that contains nested element declarations
45                    (e.g. "<!ELEMENT junk ((bar|foo|xyz+), zebra*)>").

60        Security fixes:
61            #562  CVE-2022-25235 -- Passing malformed 2- and 3-byte UTF-8
62                    sequences (e.g. from start tag names) to the XML
63                    processing application on top of Expat can cause
64                    arbitrary damage (e.g. code execution) depending
65                    on how invalid UTF-8 is handled inside the XML
66                    processor; validation was not their job but Expat's.
67                    Exploits with code execution are known to exist.
68            #561  CVE-2022-25236 -- Passing (one or more) namespace separator
69                    characters in "xmlns[:prefix]" attribute values
70                    made Expat send malformed tag names to the XML
71                    processor on top of Expat which can cause
72                    arbitrary damage (e.g. code execution) depending
73                    on such unexpectable cases are handled inside the XML
74                    processor; validation was not their job but Expat's.
75                    Exploits with code execution are known to exist.
76            #558  CVE-2022-25313 -- Fix stack exhaustion in doctype parsing
77                    that could be triggered by e.g. a 2 megabytes
78                    file with a large number of opening braces.
79                    Expected impact is denial of service or potentially
80                    arbitrary code execution.
81            #560  CVE-2022-25314 -- Fix integer overflow in function copyString;
82                    only affects the encoding name parameter at parser creation
83                    time which is often hardcoded (rather than user input),
84                    takes a value in the gigabytes to trigger, and a 64-bit
85                    machine.  Expected impact is denial of service.
86            #559  CVE-2022-25315 -- Fix integer overflow in function storeRawNames;
87                    needs input in the gigabytes and a 64-bit machine.

105                    (undefined behavior) in function XML_GetBuffer
106                    (that is also called by function XML_Parse internally)
107                    for when XML_CONTEXT_BYTES is defined to >0 (which is both
108                    common and default).
109                    Impact is denial of service or more.
110            #551  CVE-2022-23990 -- Fix unsigned integer overflow in function
111                    doProlog triggered by large content in element type
112                    declarations when there is an element declaration handler
113                    present (from a prior call to XML_SetElementDeclHandler).
114                    Impact is denial of service or more.

222        Security fixes:
223   #34 #466 #484  CVE-2013-0340/CWE-776 -- Protect against billion laughs attacks
224                    (denial-of-service; flavors targeting CPU time or RAM or both,
225                    leveraging general entities or parameter entities or both)
226                    by tracking and limiting the input amplification factor
227                    (<amplification> := (<direct> + <indirect>) / <direct>).
228                    By conservative default, amplification up to a factor of 100.0
229                    is tolerated and rejection only starts after 8 MiB of output bytes
230                    (=<direct> + <indirect>) have been processed.
231                    The fix adds the following to the API:
232                    - A new error code XML_ERROR_AMPLIFICATION_LIMIT_BREACH to
233                      signals this specific condition.
234                    - Two new API functions ..
235                      - XML_SetBillionLaughsAttackProtectionMaximumAmplification and
236                      - XML_SetBillionLaughsAttackProtectionActivationThreshold
237                      .. to further tighten billion laughs protection parameters
238                      when desired.  Please see file "doc/reference.html" for details.
239                      If you ever need to increase the defaults for non-attack XML
240                      payload, please file a bug report with libexpat.
241                    - Two new XML_FEATURE_* constants ..
242                      - that can be queried using the XML_GetFeatureList function, and
243                      - that are shown in "xmlwf -v" output.
244                    - Two new environment variable switches ..
245                      - EXPAT_ACCOUNTING_DEBUG=(0|1|2|3) and
246                      - EXPAT_ENTITY_DEBUG=(0|1)
247                      .. for runtime debugging of accounting and entity processing.
248                      Specific behavior of these values may change in the future.
249                    - Two new command line arguments "-a FACTOR" and "-b BYTES"
250                      for xmlwf to further tighten billion laughs protection
251                      parameters when desired.
252                      If you ever need to increase the defaults for non-attack XML

300Release 2.3.0 Thu March 25 2021
301        Bug fixes:
302            #438  When calling XML_ParseBuffer without a prior successful call to
303                    XML_GetBuffer as a user, no longer trigger undefined behavior
304                    (by adding an integer to a NULL pointer) but rather return
305                    XML_STATUS_ERROR and set the error code to (new) code
306                    XML_ERROR_NO_BUFFER. Found by UBSan (UndefinedBehaviorSanitizer)
307                    of Clang 11 (but not Clang 9).
308            #444  xmlwf: Exit status 2 was used for both:
309                    - malformed input files (documented) and
310                    - invalid command-line arguments (undocumented).
311                    The case of invalid command-line arguments now
312                    has its own exit status 4, resolving the ambiguity.
313
314        Other changes:
315            #439  xmlwf: Add argument -k to allow continuing after
316                    non-fatal errors

318  #422 #426 #447  Windows: Drop support for Visual Studio <=14.0/2015
319            #434  Windows: CMake: Detect unsupported Visual Studio at
320                    configure time (rather than at compile time)
321       #382 #428  testrunner: Make verbose mode (argument "-v") report
322                    about passed tests, and make default mode report about
323                    failures, as well.
324            #442  CMake: Call "enable_language(CXX)" prior to tinkering
325                    with CMAKE_CXX_* variables
326            #448  Document use of libexpat from a CMake-based project

328                    so that users with "find_package(expat [..] CONFIG [..])"
329                    are served on distributions that are *not* using the CMake
330                    build system inside for libexpat packaging
331       #436 #437  Autotools: Drop obsolescent macro AC_HEADER_STDC
332       #450 #452  Autotools: Resolve use of obsolete macro AC_CONFIG_HEADER
333            #441  Address compiler warnings
334            #443  Version info bumped from 7:12:6 to 8:0:7
335                    due to addition of error code XML_ERROR_NO_BUFFER

376       #407 #408  CMake: Keep expat target name constant at "expat"
377                    (i.e. refrain from using the target name to control
378                    build artifact filenames)

412                  examples: Drop executable bits from elements.c
413            #349  Windows: Change the name of the Windows DLLs from expat*.dll
414                    to libexpat*.dll once more (regression from 2.2.8, first
415                    fixed in 1.95.3, issue #61 on SourceForge today,
416                    was issue #432456 back then); needs a fix due
417                    case-insensitive file systems on Windows and the fact that

426        Security fixes:
427       #317 #318  CVE-2019-15903 -- Fix heap overflow triggered by
428                    XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber),
429                    and deny internal entities closing the doctype;

435            #341  xmlwf: Fix exit code for operation without "-d DIRECTORY";
436                    previously, only "-d DIRECTORY" would give you a proper
437                    exit code:
438                      # xmlwf -d . <<<'<not well-formed>' 2>/dev/null ; echo $?
439                      2

441                      0
442                    Now both cases return exit code 2.

965          #1785430: Expat build fails on linux-amd64 with gcc version>=4.1 -O3.
966          #1983953, 2517952, 2517962, 2649838:
967                Build modifications using autoreconf instead of buildconf.sh.
968          #2815947, #2884086: OBJEXT and EXEEXT support while building.
969          #2517938: xmlwf should return non-zero exit status if not well-formed.

982          Added new API member XML_SetHashSalt() that allows setting an initial
983                value (salt) for hash calculations. This is part of the fix for
984                bug #3496608 to randomize hash parameters.
985          When compiled with XML_ATTR_INFO defined, adds new API member
986                XML_GetAttributeInfo() that allows retrieving the byte
987                offsets for attribute names and values (patch #3446384).
988          Added CMake build system.
989                See bug #2990652 and patch #3312568.
990          Added run-benchmark target to Makefile.in - relies on testdata module
991                present in the same relative location as in the repository.
992
993Release 2.0.1 Tue June 5 2007
994        - Fixed bugs #1515266, #1515600: The character data handler's calling
995          of XML_StopParser() was not handled properly; if the parser was
996          stopped and the handler set to NULL, the parser would segfault.
997        - Fixed bug #1690883: Expat failed on EBCDIC systems as it assumed
998          some character constants to be ASCII encoded.
999        - Minor cleanups of the test harness.
1000        - Fixed xmlwf bug #1513566: "out of memory" error on file size zero.
1001        - Fixed outline.c bug #1543233: missing a final XML_ParserFree() call.
1002        - Fixes and improvements for Windows platform:
1003          bugs #1409451, #1476160, #1548182, #1602769, #1717322.
1004        - Build fixes for various platforms:
1005          HP-UX, Tru64, Solaris 9: patch #1437840, bug #1196180.
1006          All Unix: #1554618 (refreshed config.sub/config.guess).
1007                    #1490371, #1613457: support both, DESTDIR and INSTALL_ROOT,
1008                    without relying on GNU-Make specific features.
1009          #1647805: Patched configure.in to work better with Intel compiler.
1010        - Fixes to Makefile.in to have make check work correctly:
1011          bugs #1408143, #1535603, #1536684.
1012        - Added Open Watcom support: patch #1523242.
1013
1014Release 2.0.0 Wed Jan 11 2006
1015        - We no longer use the "check" library for C unit testing; we
1016          always use the (partial) internal implementation of the API.
1017        - Report XML_NS setting via XML_GetFeatureList().
1018        - Fixed headers for use from C++.
1019        - XML_GetCurrentLineNumber() and  XML_GetCurrentColumnNumber()
1020          now return unsigned integers.
1021        - Added XML_LARGE_SIZE switch to enable 64-bit integers for
1022          byte indexes and line/column numbers.
1023        - Updated to use libtool 1.5.22 (the most recent).
1024        - Added support for AmigaOS.
1025        - Some mostly minor bug fixes. SF issues include: #1006708,
1026          #1021776, #1023646, #1114960, #1156398, #1221160, #1271642.
1027
1028Release 1.95.8 Fri Jul 23 2004
1029        - Major new feature: suspend/resume.  Handlers can now request
1030          that a parse be suspended for later resumption or aborted
1031          altogether.  See "Temporarily Stopping Parsing" in the
1032          documentation for more details.
1033        - Some mostly minor bug fixes, but compilation should no
1034          longer generate warnings on most platforms.  SF issues
1035          include: #827319, #840173, #846309, #888329, #896188, #923913,
1036          #928113, #961698, #985192.
1037
1038Release 1.95.7 Mon Oct 20 2003
1039        - Fixed enum XML_Status issue (reported on SourceForge many
1040          times), so compilers that are properly picky will be happy.
1041        - Introduced an XMLCALL macro to control the calling
1042          convention used by the Expat API; this macro should be used
1043          to annotate prototypes and definitions of callback
1044          implementations in code compiled with a calling convention
1045          other than the default convention for the host platform.
1046        - Improved ability to build without the configure-generated
1047          expat_config.h header.  This is useful for applications
1048          which embed Expat rather than linking in the library.
1049        - Fixed a variety of bugs: see SF issues #458907, #609603,
1050          #676844, #679754, #692878, #692964, #695401, #699323, #699487,
1051          #820946.
1052        - Improved hash table lookups.
1053        - Added more regression tests and improved documentation.
1054
1055Release 1.95.6 Tue Jan 28 2003
1056        - Added XML_FreeContentModel().
1057        - Added XML_MemMalloc(), XML_MemRealloc(), XML_MemFree().
1058        - Fixed a variety of bugs: see SF issues #615606, #616863,
1059          #618199, #653180, #673791.
1060        - Enhanced the regression test suite.
1061        - Man page improvements: includes SF issue #632146.
1062
1063Release 1.95.5 Fri Sep 6 2002
1064        - Added XML_UseForeignDTD() for improved SAX2 support.
1065        - Added XML_GetFeatureList().
1066        - Defined XML_Bool type and the values XML_TRUE and XML_FALSE.
1067        - Use an incomplete struct instead of a void* for the parser
1068          (may not retain).
1069        - Fixed UTF-8 decoding bug that caused legal UTF-8 to be rejected.
1070        - Finally fixed bug where default handler would report DTD
1071          events that were already handled by another handler.
1072          Initial patch contributed by Darryl Miles.
1073        - Removed unnecessary DllMain() function that caused static
1074          linking into a DLL to be difficult.
1075        - Added VC++ projects for building static libraries.
1076        - Reduced line-length for all source code and headers to be
1077          no longer than 80 characters, to help with AS/400 support.
1078        - Reduced memory copying during parsing (SF patch #600964).
1079        - Fixed a variety of bugs: see SF issues #580793, #434664,
1080          #483514, #580503, #581069, #584041, #584183, #584832, #585537,
1081          #596555, #596678, #598352, #598944, #599715, #600479, #600971.
1082
1083Release 1.95.4 Fri Jul 12 2002

1099Release 1.95.3 Mon Jun 3 2002
1100        - Added a project to the MSVC workspace to create a wchar_t
1101          version of the library; the DLLs are named libexpatw.dll.
1102        - Changed the name of the Windows DLLs from expat.dll to
1103          libexpat.dll; this fixes SF bug #432456.
1104        - Added the XML_ParserReset() API function.
1105        - Fixed XML_SetReturnNSTriplet() to work for element names.
1106        - Made the XML_UNICODE builds usable (thanks, Karl!).
1107        - Allow xmlwf to read from standard input.
1108        - Install a man page for xmlwf on Unix systems.
1109        - Fixed many bugs; see SF bug reports #231864, #461380, #464837,

1111          #547350.  Other bugs which we can't test as easily may also
1112          have been fixed, especially in the area of build support.
1113
1114Release 1.95.2 Fri Jul 27 2001
1115        - More changes to make MSVC happy with the build; add a single
1116          workspace to support both the library and xmlwf application.
1117        - Added a Windows installer for Windows users; includes
1118          xmlwf.exe.
1119        - Added compile-time constants that can be used to determine the
1120          Expat version
1121        - Removed a lot of GNU-specific dependencies to aide portability
1122          among the various Unix flavors.
1123        - Fix the UTF-8 BOM bug.
1124        - Cleaned up warning messages for several compilers.
1125        - Added the -Wall, -Wstrict-prototypes options for GCC.

1128        - Changes to get expat to build under Microsoft compiler
1129        - Removed all aborts and instead return an UNEXPECTED_STATE error.
1130        - Fixed a bug where a stray '%' in an entity value would cause an
1131          abort.
1132        - Defined XML_SetEndNamespaceDeclHandler. Thanks to Darryl Miles for
1133          finding this oversight.
1134        - Changed default patterns in lib/Makefile.in to fit non-GNU makes
1135          Thanks to robin@unrated.net for reporting and providing an
1136          account to test on.
1137        - The reference had the wrong label for XML_SetStartNamespaceDecl.
1138          Reported by an anonymous user.
1139
1140Release 1.95.0 Fri Sep 29 2000
1141        - XML_ParserCreate_MM
1142                Allows you to set a memory management suite to replace the
1143                standard malloc,realloc, and free.
1144        - XML_SetReturnNSTriplet
1145                If you turn this feature on when namespace processing is in
1146                effect, then qualified, prefixed element and attribute names
1147                are returned as "uri|name|prefix" where '|' is whatever
1148                separator character is used in namespace processing.
1149        - Merged in features from perl-expat
1150                o XML_SetElementDeclHandler
1151                o XML_SetAttlistDeclHandler
1152                o XML_SetXmlDeclHandler
1153                o XML_SetEntityDeclHandler
1154                o StartDoctypeDeclHandler takes 3 additional parameters:
1155                        sysid, pubid, has_internal_subset
1156                o Many paired handler setters (like XML_SetElementHandler)
1157                  now have corresponding individual handler setters
1158                o XML_GetInputContext for getting the input context of
1159                  the current parse position.
1160        - Added reference material
1161        - Packaged into a distribution that builds a sharable library
