!! <blink>Expat is UNDERSTAFFED and WITHOUT FUNDING.</blink> !!
!! ~~~~~~~~~~~~ !!
!! The following topics need *additional skilled C developers* to progress !!
!! in a timely manner or at all (loosely ordered by descending priority): !!
!! !!
!! - <blink>fixing a complex non-public security issue</blink>, !!
!! - teaming up on researching and fixing future security reports and !!
!! ClusterFuzz findings with few-days-max response times in communication !!
!! in order to (1) have a sound fix ready before the end of a 90 days !!
!! grace period and (2) in a sustainable manner, !!
!! - implementing and auto-testing XML 1.0r5 support !!
!! (needs discussion before pull requests), !!
!! - smart ideas on fixing the Autotools CMake files generation issue !!
!! without breaking CI (needs discussion before pull requests), !!
!! - the Windows binaries topic (needs requirements engineering first), !!
!! - pushing migration from `int` to `size_t` further !!
!! including edge-cases test coverage (needs discussion before anything). !!
!! !!
!! For details, please reach out via e-mail to sebastian@pipping.org so we !!
!! can schedule a voice call on the topic, in English or German. !!

Release 2.6.3 Wed September 4 2024
Security fixes:
#887 #890 CVE-2024-45490 -- Calling function XML_ParseBuffer with
len < 0 without noticing and then calling XML_GetBuffer
will have XML_ParseBuffer fail to recognize the problem
and XML_GetBuffer corrupt memory.
With the fix, XML_ParseBuffer now complains with error
XML_ERROR_INVALID_ARGUMENT just like sibling XML_Parse
has been doing since Expat 2.2.1, and now documented.
Impact is denial of service to potentially artitrary code
execution.
#888 #891 CVE-2024-45491 -- Internal function dtdCopy can have an
integer overflow for nDefaultAtts on 32-bit platforms
(where UINT_MAX equals SIZE_MAX).
Impact is denial of service to potentially artitrary code
execution.
#889 #892 CVE-2024-45492 -- Internal function nextScaffoldPart can
have an integer overflow for m_groupSize on 32-bit
platforms (where UINT_MAX equals SIZE_MAX).
Impact is denial of service to potentially artitrary code
execution.
Other changes:
#851 #879 Autotools: Sync CMake templates with CMake 3.28
#853 Autotools: Always provide path to find(1) for portability

This directory contains the test suite for Expat. The tests provide
general unit testing and regression coverage. The tests are not
expected to be useful examples of Expat usage; see the
[examples](../examples) directory for that.
The Expat tests use a partial internal implementation of the

C.
Expat must be built and, on some platforms, installed, before the

This directory contains the (fledgling) test suite for Expat. The
tests provide general unit testing and regression coverage. The tests
are not expected to be useful examples of Expat usage; see the
examples/ directory for that.
The Expat tests use a partial internal implementation of the "Check"
unit testing framework for C. More information on Check can be found at:
http://check.sourceforge.net/
Expat must be built and, depending on platform, must be installed, before "make check" can be executed.
This test suite can all change in a later version.
