Release 2.2.1 Sat June 17 2017
Security fixes:
CVE-2017-9233 -- External entity infinite loop DoS
Details: https://libexpat.github.io/doc/cve-2017-9233/
Commit c4bf96bb51dd2a1b0e185374362ee136fe2c9d7f
[MOX-002] CVE-2016-9063 -- Detect integer overflow; commit
d4f735b88d9932bd5039df2335eefdd0723dbe20
(Fixed version of existing downstream patches!)
(SF.net) #539 Fix regression from fix to CVE-2016-0718 cutting off
longer tag names; commits
* 896b6c1fd3b842f377d1b62135dccf0a579cf65d
* af507cef2c93cb8d40062a0abe43a4f4e9158fb2
#16 * 0dbbf43fdb20f593ddf4fa1ff67288000dd4a7fd
#25 More integer overflow detection (function poolGrow); commits
* 810b74e4703dcfdd8f404e3cb177d44684775143
* 44178553f3539ce69d34abee77a05e879a7982ac
[MOX-002] Detect overflow from len=INT_MAX call to XML_Parse; commits
* 4be2cb5afcc018d996f34bbbce6374b7befad47f
* 7e5b71b748491b6e459e5c9a1d090820f94544d8
[MOX-005] #30 Use high quality entropy for hash initialization:
* arc4random_buf on BSD, systems with libbsd
(when configured with --with-libbsd), CloudABI
* RtlGenRandom on Windows XP / Server 2003 and later
* getrandom on Linux 3.17+
In a way, that's still part of CVE-2016-5300.

[MOX-005] For the low quality entropy extraction fallback code,
the parser instance address can no longer leak, commit

[MOX-001] #35 Change hash algorithm to William Ahern's version of SipHash
to go further with fixing CVE-2012-0876.
https://github.com/libexpat/libexpat/pull/39/commits
Bug fixes:
#32 Fix sharing of hash salt across parsers;
relevant where XML_ExternalEntityParserCreate is called
prior to XML_Parse, in particular (e.g. FBReader)
#28 xmlwf: Auto-disable use of memory-mapping (and parsing
as a single chunk) for files larger than ~1 GB (2^30 bytes)
rather than failing with error "out of memory"
#3 Fix double free after malloc failure in DTD code; commit
7ae9c3d3af433cd4defe95234eae7dc8ed15637f
#17 Fix memory leak on parser error for unbound XML attribute
prefix with new namespaces defined in the same tag;
found by Google's OSS-Fuzz; commits
* 16f87daae5a16132e479e4f71862128c7a915c73
* b47dbc9745932c160893d433220e462bd605f8cd
xmlwf on Windows: Add missing calls to CloseHandle
New features:
#30 Introduced environment switch EXPAT_ENTROPY_DEBUG=1
for runtime debugging of entropy extraction
Other changes:
Increase code coverage
#33 Reject use of XML_UNICODE_WCHAR_T with sizeof(wchar_t) != 2;
XML_UNICODE_WCHAR_T was never meant to be used outside
of Windows; 4-byte wchar_t is common on Linux
(SF.net) #538 Start using -fno-strict-aliasing
(SF.net) #540 Support compilation against cloudlibc of CloudABI
Allow MinGW cross-compilation
(SF.net) #534 CMake: Introduce option "BUILD_doc" (enabled by default)
to bypass compilation of the xmlwf.1 man page
(SF.net) pr2 CMake: Introduce option "INSTALL" (enabled by default)
to bypass installation of expat files
CMake: Fix ninja support
Autotools: Add parameters --enable-xml-context [COUNT]
and --disable-xml-context; default of context of 1024
bytes enabled unchanged
#14 Drop AmigaOS 4.x code and includes
#14 Drop ancient build systems:
* Borland C++ Builder
* OpenVMS
* Open Watcom
* Visual Studio 6.0
* Pre-X Mac OS (MPW Makefile)
If you happen to rely on some of these, please get in
touch for joining with maintenance.
#10 Move from WIN32 to _WIN32
#13 Fix "make run-xmltest" order instability
