jpayne@68: !! !!
jpayne@68: !! - , !!
jpayne@68: !! - teaming up on researching and fixing future security reports and !!
jpayne@68: !! ClusterFuzz findings with few-days-max response times in communication !!
jpayne@68: !! in order to (1) have a sound fix ready before the end of a 90 days !!
jpayne@68: !! grace period and (2) in a sustainable manner, !!
jpayne@68: !! - implementing and auto-testing XML 1.0r5 support !!
jpayne@68: !! (needs discussion before pull requests), !!
jpayne@68: !! - smart ideas on fixing the Autotools CMake files generation issue !!
jpayne@68: !! without breaking CI (needs discussion before pull requests), !!
jpayne@68: !! - the Windows binaries topic (needs requirements engineering first), !!
jpayne@68: !! - pushing migration from `int` to `size_t` further !!

jpayne@68: sequences (e.g. from start tag names) to the XML
jpayne@68: processing application on top of Expat can cause
jpayne@68: arbitrary damage (e.g. code execution) depending
jpayne@68: on how invalid UTF-8 is handled inside the XML
jpayne@68: processor; validation was not their job but Expat's.
jpayne@68: Exploits with code execution are known to exist.
jpayne@68: #561 CVE-2022-25236 -- Passing (one or more) namespace separator
jpayne@68: characters in "xmlns[:prefix]" attribute values

jpayne@68: only affects the encoding name parameter at parser creation
jpayne@68: time which is often hardcoded (rather than user input),
jpayne@68: takes a value in the gigabytes to trigger, and a 64-bit

jpayne@68: If you ever need to increase the defaults for non-attack XML
jpayne@68: payload, please file a bug report with libexpat.
jpayne@68: - Two new XML_FEATURE_* constants ..
jpayne@68: - that can be queried using the XML_GetFeatureList function, and

jpayne@68: Security fixes:
jpayne@68: #317 #318 CVE-2019-15903 -- Fix heap overflow triggered by

jpayne@68: and deny internal entities closing the doctype;
jpayne@68: fixed in commit c20b758c332d9a13afbbb276d30db1d183a85d43
jpayne@68:
jpayne@68: Bug fixes:

jpayne@68: as a single chunk) for files larger than ~1 GB (2^30 bytes)

jpayne@68: #1785430: Expat build fails on linux-amd64 with gcc version>=4.1 -O3.
jpayne@68: #1983953, 2517952, 2517962, 2649838:

jpayne@68:
jpayne@68: Release 2.0.1 Tue June 5 2007
jpayne@68: - Fixed bugs #1515266, #1515600: The character data handler's calling
jpayne@68: of XML_StopParser() was not handled properly; if the parser was
jpayne@68: stopped and the handler set to NULL, the parser would segfault.
jpayne@68: - Fixed bug #1690883: Expat failed on EBCDIC systems as it assumed
jpayne@68: some character constants to be ASCII encoded.
jpayne@68: - Minor cleanups of the test harness.
jpayne@68: - Fixed xmlwf bug #1513566: "out of memory" error on file size zero.

jpayne@68: All Unix: #1554618 (refreshed config.sub/config.guess).
jpayne@68: #1490371, #1613457: support both, DESTDIR and INSTALL_ROOT,
jpayne@68: without relying on GNU-Make specific features.
jpayne@68: #1647805: Patched configure.in to work better with Intel compiler.
jpayne@68: - Fixes to Makefile.in to have make check work correctly:
jpayne@68: bugs #1408143, #1535603, #1536684.

jpayne@68:
jpayne@68: Release 2.0.0 Wed Jan 11 2006
jpayne@68: - We no longer use the "check" library for C unit testing; we
jpayne@68: always use the (partial) internal implementation of the API.
jpayne@68: - Report XML_NS setting via XML_GetFeatureList().
jpayne@68: - Fixed headers for use from C++.
jpayne@68: - XML_GetCurrentLineNumber() and XML_GetCurrentColumnNumber()
jpayne@68: now return unsigned integers.
jpayne@68: - Added XML_LARGE_SIZE switch to enable 64-bit integers for
jpayne@68: byte indexes and line/column numbers.
jpayne@68: - Updated to use libtool 1.5.22 (the most recent).

jpayne@68:
jpayne@68: Release 1.95.8 Fri Jul 23 2004
jpayne@68: - Major new feature: suspend/resume. Handlers can now request
jpayne@68: that a parse be suspended for later resumption or aborted
jpayne@68: altogether. See "Temporarily Stopping Parsing" in the
jpayne@68: documentation for more details.
jpayne@68: - Some mostly minor bug fixes, but compilation should no
jpayne@68: longer generate warnings on most platforms. SF issues

jpayne@68:
jpayne@68: Release 1.95.7 Mon Oct 20 2003
jpayne@68: - Fixed enum XML_Status issue (reported on SourceForge many
jpayne@68: times), so compilers that are properly picky will be happy.
jpayne@68: - Introduced an XMLCALL macro to control the calling
jpayne@68: convention used by the Expat API; this macro should be used
jpayne@68: to annotate prototypes and definitions of callback
jpayne@68: implementations in code compiled with a calling convention
jpayne@68: other than the default convention for the host platform.
jpayne@68: - Improved ability to build without the configure-generated
jpayne@68: expat_config.h header. This is useful for applications
jpayne@68: which embed Expat rather than linking in the library.
jpayne@68: - Fixed a variety of bugs: see SF issues #458907, #609603,
jpayne@68: #676844, #679754, #692878, #692964, #695401, #699323, #699487,

jpayne@68: #618199, #653180, #673791.
jpayne@68: - Enhanced the regression test suite.
jpayne@68: - Man page improvements: includes SF issue #632146.
jpayne@68:
jpayne@68: Release 1.95.5 Fri Sep 6 2002
jpayne@68: - Added XML_UseForeignDTD() for improved SAX2 support.
jpayne@68: - Added XML_GetFeatureList().
jpayne@68: - Defined XML_Bool type and the values XML_TRUE and XML_FALSE.
jpayne@68: - Use an incomplete struct instead of a void* for the parser
jpayne@68: (may not retain).
jpayne@68: - Fixed UTF-8 decoding bug that caused legal UTF-8 to be rejected.
jpayne@68: - Finally fixed bug where default handler would report DTD
jpayne@68: events that were already handled by another handler.
jpayne@68: Initial patch contributed by Darryl Miles.
jpayne@68: - Removed unnecessary DllMain() function that caused static
jpayne@68: linking into a DLL to be difficult.
jpayne@68: - Added VC++ projects for building static libraries.
jpayne@68: - Reduced line-length for all source code and headers to be
jpayne@68: no longer than 80 characters, to help with AS/400 support.
jpayne@68: - Reduced memory copying during parsing (SF patch #600964).
jpayne@68: - Fixed a variety of bugs: see SF issues #580793, #434664,
jpayne@68: #483514, #580503, #581069, #584041, #584183, #584832, #585537,
jpayne@68: #596555, #596678, #598352, #598944, #599715, #600479, #600971.
jpayne@68:
jpayne@68: Release 1.95.4 Fri Jul 12 2002

jpayne@68: - Re-implemented section 5.1 from XML 1.0 spec:
jpayne@68: see SF bug report #570263 and SF patch #578161
jpayne@68:
jpayne@68: Release 1.95.3 Mon Jun 3 2002
jpayne@68: - Added a project to the MSVC workspace to create a wchar_t
jpayne@68: version of the library; the DLLs are named libexpatw.dll.
jpayne@68: - Changed the name of the Windows DLLs from expat.dll to
jpayne@68: libexpat.dll; this fixes SF bug #432456.
jpayne@68: - Added the XML_ParserReset() API function.
jpayne@68: - Fixed XML_SetReturnNSTriplet() to work for element names.
jpayne@68: - Made the XML_UNICODE builds usable (thanks, Karl!).

jpayne@68: - Cleaned up warning messages for several compilers.
jpayne@68: - Added the -Wall, -Wstrict-prototypes options for GCC.
jpayne@68:
jpayne@68: Release 1.95.1 Sun Oct 22 15:11:36 EDT 2000
jpayne@68: - Changes to get expat to build under Microsoft compiler

jpayne@68: standard malloc,realloc, and free.
jpayne@68: - XML_SetReturnNSTriplet
jpayne@68: If you turn this feature on when namespace processing is in

jpayne@68: separator character is used in namespace processing.
jpayne@68: - Merged in features from perl-expat
jpayne@68: o XML_SetElementDeclHandler
