Release 2.2.8 Fri Septemper 13 2019
Security fixes:
#317 #318 CVE-2019-15903 -- Fix heap overflow triggered by
XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber),
and deny internal entities closing the doctype;
fixed in commit c20b758c332d9a13afbbb276d30db1d183a85d43
Bug fixes:
#240 Fix cases where XML_StopParser did not have any effect
when called from inside of an end element handler
#341 xmlwf: Fix exit code for operation without "-d DIRECTORY";
previously, only "-d DIRECTORY" would give you a proper
exit code:
# xmlwf -d . <<<'<not well-formed>' 2>/dev/null ; echo $?
2
# xmlwf <<<'<not well-formed>' 2>/dev/null ; echo $?
0
Now both cases return exit code 2.
Other changes:
#299 #302 Windows: Replace LoadLibrary hack to access
unofficial API function SystemFunction036 (RtlGenRandom)
by using official API function rand_s (needs WinXP+)
#325 Windows: Drop support for Visual Studio <=7.1/2003
and document supported compilers in README.md
#286 Windows: Remove COM code from xmlwf; in case it turns
out needed later, there will be a dedicated repository
below https://github.com/libexpat/ for that code
#322 Windows: Remove explicit MSVC solution and project files.
You can generate Visual Studio solution files through
CMake, e.g.: cmake -G"Visual Studio 15 2017" .

Security issues fixed:
CVE-2017-9233, CVE-2016-9063, improve fix for CVE-2016-5300

Cleanup: Drop AmigaOS 4.x, Borland C++ Builder, OpenVMS, Open Watcom,
Visual Studio 6.0 and Pre-X Mac OS support
|

changes:
-security patches which we already had in pkgsrc are integrated
-Use more entropy for hash initialization than the original fix

on malformed input (CVE-2016-0718)
Description: The Expat XML parser mishandles certain kinds of malformed
input documents, resulting in buffer overflows during processing and error
reporting. The overflows can manifest as a segmentation fault or as memory
corruption during a parse operation. The bugs allow for a denial of service
attack in many applications by an unauthenticated attacker, and could
conceivably result in remote code execution.
bump PKGREV
also add an improvement to the fix for CVE-2015-1283 which was part
of the 2.1.1 release -- don't rely on defined behaviour on overflows
of signed integer operations, from upstream git:
https://sourceforge.net/p/expat/code_git/ci/f0bec73b018caa07d3e75ec8dd967f3785d71bde/
pkgsrc change: add a hint how to run the pkg's selftest (not enabled
permanently because this would add a dependency on C++)

Not necessary and cuases problems.

#2517946: Wrong statement about XMLDecl in xmlwf.1 and xmlwf.sgml.
#2855609: Dangling positionPtr after error.
#2894085: CVE-2009-3560 - Buffer over-read and crash in big2_toUtf8().
#2958794: CVE-2012-1148 - Memory leak in poolGrow.

#3010819: UNEXPECTED_STATE with a trailing "%" in entity value.
#3206497: Unitialized memory returned from XML_Parse.
#3287849: make check fails on mingw-w64.
#3496608: CVE-2012-0876 - Hash DOS attack.
- Patches:
#1749198: pkg-config support.
#3010222: Fix for bug #3010819.
#3312568: CMake support.
#3446384: Report byte offsets for attr names and values.
- New Features / API changes:
Added new API member XML_SetHashSalt() that allows setting an intial
value (salt) for hash calculations. This is part of the fix for
bug #3496608 to randomize hash parameters.
When compiled with XML_ATTR_INFO defined, adds new API member
XML_GetAttributeInfo() that allows retrieving the byte
offsets for attribute names and values (patch #3446384).
Added CMake build system.
See bug #2990652 and patch #3312568.
Added run-benchmark target to Makefile.in - relies on testdata module
present in the same relative location as in the repository.

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

X.Org found in NetBSD-current.
Thanks a lot to all who helped, especially Matthias Scheler who did
repeated tests on Mac OS X and older versions of NetBSD to make sure the
support for those platforms wouldn't be broken (or at least, not fatally,
as I would still expect a few hiccups here and there, because there is
only so much one can test in such limited time).
On the infrastructure side, this branch brings pkgconfig-builtin.mk, in
order to write very easily new builtin.mk files. It can actually handle
more than just pkgconfig files, but it will provide a version if it finds
such a file. x11.builtin.mk has also been made more useful and now all
existing (and future!) native-X11-related builtin.mk files should include
it.

Release 2.0.1 Tue June 5 2007
- Fixed bugs #1515266, 1515600: The character data handler's calling
of XML_StopParser() was not handled properly; if the parser was
stopped and the handler set to NULL, the parser would segfault.
- Fixed bug #1690883: Expat failed on EBCDIC systems as it assumed
some character constants to be ASCII encoded.
- Minor cleanups of the test harness.
- Fixed xmlwf bug #1513566: "out of memory" error on file size zero.
- Fixed outline.c bug #1543233: missing a final XML_ParserFree() call.
- Fixes and improvements for Windows platform:
bugs #1409451, #1476160, 1548182, 1602769, 1717322.
- Build fixes for various platforms:
HP-UX, Tru64, Solaris 9: patch #1437840, bug #1196180.
All Unix: #1554618 (refreshed config.sub/config.guess).
#1490371, #1613457: support both, DESTDIR and INSTALL_ROOT,
without relying on GNU-Make specific features.
#1647805: Patched configure.in to work better with Intel compiler.
- Fixes to Makefile.in to have make check work correctly:
bugs #1408143, #1535603, #1536684.
- Added Open Watcom support: patch #1523242.

and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at

RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).

Release 2.0.0 Wed Jan 11 2006
- We no longer use the "check" library for C unit testing; we
always use the (partial) internal implementation of the API.
- Report XML_NS setting via XML_GetFeatureList().
- Fixed headers for use from C++.
- XML_GetCurrentLineNumber() and XML_GetCurrentColumnNumber()
now return unsigned integers.
- Added XML_LARGE_SIZE switch to enable 64-bit integers for
byte indexes and line/column numbers.
- Updated to use libtool 1.5.22 (the most recent).
- Added support for AmigaOS.
- Some mostly minor bug fixes. SF issues include: 1006708,
1021776, 1023646, 1114960, 1156398, 1221160, 1271642.
