* Security fixes:
- CVE-2024-45490, bsc#1229930 -- 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.
- CVE-2024-45491, bsc#1229931 -- 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.
- CVE-2024-45492, bsc#1229932 -- 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:
- Autotools: Sync CMake templates with CMake 3.28

- Update keyring automatically from keyserver during OBS service run.
- Explicitly use --without-docbook (before it was implicit).
- Include missing files for documentation and examples.
- Add manpage for xmlwf, which is not available in the release tarball.
- Clean the spec file a bit.
- Update to 2.6.0:
* Security fixes:
- CVE-2023-52425 (boo#1219559)
-- Fix quadratic runtime issues with big tokens
that can cause denial of service, in partial where
dealing with compressed XML input. Applications
that parsed a document in one go -- a single call to
functions XML_Parse or XML_ParseBuffer -- were not affected.
The smaller the chunks/buffers you use for parsing
previously, the bigger the problem prior to the fix.
Backporters should be careful to no omit parts of
pull request #789 and to include earlier pull request #771,
in order to not break the fix.
- CVE-2023-52426 (boo#1219561)
-- Fix billion laughs attacks for users
compiling *without* XML_DTD defined (which is not common).
Users with XML_DTD defined have been protected since
Expat >=2.4.0 (and that was CVE-2013-0340 back then).
* Bug fixes:
- Fix parse-size-dependent "invalid token" error for
external entities that start with a byte order mark
- Fix NULL pointer dereference in setContext via
XML_ExternalEntityParserCreate for compilation with
XML_DTD undefined
- Protect against closing entities out of order

* Security fixes:
- CVE-2022-43680 -- Fix heap use-after-free after overeager
destruction of a shared DTD in function
XML_ExternalEntityParserCreate in out-of-memory situations.
Expected impact is denial of service or potentially arbitrary
code execution.

- Fix case when parsing was suspended while processing nested
entities
- Stop leaking opening tag bindings after a closing tag mismatch
error where a parser is reset through XML_ParserReset and then
reused to parse
- CMake: Fix generation of pkg-config file
- MinGW|CMake: Fix static library name
* Other changes:
- Protect header expat_config.h from multiple inclusion
- examples: Make use of XML_GetBuffer and be more consistent
across examples

linking with -DEXPAT_DTD=OFF and/or -DEXPAT_ATTR_INFO=ON
- MinGW|CMake: Apply MSVC .def file when linking

i.e. produce libexpat-1.dll rather than libexpat.dll
by default. Filename libexpat.dll.a is unaffected.
- MinGW|CMake: Set missing variable CMAKE_RC_COMPILER in
toolchain file "cmake/mingw-toolchain.cmake" to avoid
error "windres: Command not found" on e.g. Ubuntu 20.04
- CMake: Unify inconsistent use of set() and option() in
context of public build time options to take need for

- udpate to 2.4.7 (bsc#1196784, CVE-2022-25236):
* Bug fixes:
- Relax fix to CVE-2022-25236 (introduced with release 2.4.5)
with regard to all valid URI characters (RFC 3986),
i.e. the following set (excluding whitespace):
ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz
0123456789 % -._~ :/?#[]@ !$&'()*+,;=
* Other changes:
- CMake|Windows: Store Expat version in the DLL
- Document consequences of namespace separator choices not just
in doc/reference.html but also in header <expat.h>
- Document Expat's lack of validation of namespace URIs against
RFC 3986, and that the XML 1.0r4 specification doesn't
require Expat to validate namespace URIs, and that Expat
may do more in that regard in future releases.
If you find need for strict RFC 3986 URI validation on
application level today, https://uriparser.github.io/ may
be of interest.
- Fix documentation of XML_EndDoctypeDeclHandler in <expat.h>
- Document that a call to XML_FreeContentModel can be done at
a later time from outside the element declaration handler
- Make hardcoded namespace URIs easier to find in code
- Update documentation on use of XML_POOR_ENTOPY on Solaris
- tests: Resolve use of macros NAN and INFINITY for GNU G++
4.8.2 on Solaris.

* Security fixes:
- CVE-2022-25235 -- Passing malformed 2- and 3-byte UTF-8
sequences (e.g. from start tag names) to the XML
processing application on top of Expat can cause
arbitrary damage (e.g. code execution) depending
on how invalid UTF-8 is handled inside the XML
processor; validation was not their job but Expat's.
Exploits with code execution are known to exist.
- CVE-2022-25236 -- Passing (one or more) namespace separator
characters in "xmlns[:prefix]" attribute values

arbitrary damage (e.g. code execution) depending

- Update to 2.4.0: [CVE-2013-0340 "Billion Laughs"]
* Security fixes:
- CVE-2013-0340/CWE-776 -- Protect against billion laughs attacks
(denial-of-service; flavors targeting CPU time or RAM or both,
leveraging general entities or parameter entities or both)
by tracking and limiting the input amplification factor
(<amplification> := (<direct> + <indirect>) / <direct>).
By conservative default, amplification up to a factor of 100.0
is tolerated and rejection only starts after 8 MiB of output bytes
(=<direct> + <indirect>) have been processed.
The fix adds the following to the API:
- A new error code XML_ERROR_AMPLIFICATION_LIMIT_BREACH to
signals this specific condition.
- Two new API functions ..
- XML_SetBillionLaughsAttackProtectionMaximumAmplification and
- XML_SetBillionLaughsAttackProtectionActivationThreshold
.. to further tighten billion laughs protection parameters
when desired. Please see file "doc/reference.html" for details.
If you ever need to increase the defaults for non-attack XML
payload, please file a bug report with libexpat.
- Two new XML_FEATURE_* constants ..
- that can be queried using the XML_GetFeatureList function, and

- update to 2.3.0:
* When calling XML_ParseBuffer without a prior successful call to
XML_GetBuffer as a user, no longer trigger undefined behavior

XML_STATUS_ERROR and set the error code to (new) code
XML_ERROR_NO_BUFFER. Found by UBSan (UndefinedBehaviorSanitizer)
of Clang 11 (but not Clang 9).
* xmlwf: Exit status 2 was used for both:
- malformed input files (documented) and
- invalid command-line arguments (undocumented).
case of invalid command-line arguments now
has its own exit status 4, resolving the ambiguity.
