- 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.
- Version info bumped from 9:6:8 to 9:7:8;

bsc#1196026, bsc#1196025):
* 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
made Expat send malformed tag names to the XML
processor on top of Expat which can cause
arbitrary damage (e.g. code execution) depending
on such unexpectable cases are handled inside the XML
processor; validation was not their job but Expat's.
Exploits with code execution are known to exist.
- CVE-2022-25313 -- Fix stack exhaustion in doctype parsing
that could be triggered by e.g. a 2 megabytes
file with a large number of opening braces.
Expected impact is denial of service or potentially
arbitrary code execution.
- CVE-2022-25314 -- Fix integer overflow in function copyString;
only affects the encoding name parameter at parser creation
time which is often hardcoded (rather than user input),
takes a value in the gigabytes to trigger, and a 64-bit
machine. Expected impact is denial of service.
- CVE-2022-25315 -- Fix integer overflow in function storeRawNames;
needs input in the gigabytes and a 64-bit machine.

(undefined behavior) in function XML_GetBuffer
that is also called by function XML_Parse internally)
for when XML_CONTEXT_BYTES is defined to >0 (which is both
common and default).
Impact is denial of service or more.
- CVE-2022-23990 -- Fix unsigned integer overflow in function
doProlog triggered by large content in element type
declarations when there is an element declaration handler
present (from a prior call to XML_SetElementDeclHandler).
Impact is denial of service or more.
* Bug fixes:
- xmlwf: Fix a memory leak on output file opening error
* Other changes:
- Version info bumped from 9:3:8 to 9:4:8;

* CVE-2021-45960 -- Fix issues with left shifts by >=29 places
resulting in
a) realloc acting as free
b) realloc allocating too few bytes
c) undefined behavior
depending on architecture and precise value
for XML documents with >=2^27+1 prefixed attributes
on a single XML tag a la
"<r xmlns:a='[..]' a:a123='[..]' [..] />"
where XML_ParserCreateNS is used to create the parser
(which needs argument "-n" when running xmlwf).
Impact is denial of service, or more.
* CVE-2021-46143 (ZDI-CAN-16157) -- Fix integer overflow
on variable m_groupSize in function doProlog leading
to realloc acting as free.
Impact is denial of service or more.

- 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

OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/expat?expand=0&rev=88
- 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
(by adding an integer to a NULL pointer) but rather return
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.

#2958794: CVE-2012-1148 - Memory leak in poolGrow.
#2990652: CMake support.
#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.
- update to 2.1.0 beta
* refreshed expat-visibility.patch
* removed obsolete expat-CVE-2009-3560.patch
* removed obsolete expat-CVE-2009-2625.patch

( from Changes )
* 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.

some character constants to be ASCII encoded.
* Minor cleanups of the test harness.

#1647805: Patched configure.in to work better with Intel compiler.
* Fixes to Makefile.in to have make check work correctly:
bugs #1408143, #1535603, #1536684.

CVE-2017-9233 / bsc#1047236 -- External entity infinite loop DoS
Details: https://libexpat.github.io/doc/cve-2017-9233/
Commit c4bf96bb51dd2a1b0e185374362ee136fe2c9d7f
- [MOX-002] CVE-2016-9063 / bsc#1047240 -- Detect integer overflow;
(Fixed version of existing downstream patches!)
- (SF.net) #539 Fix regression from fix to CVE-2016-0718 cutting off
longer tag names;
#25 More integer overflow detection (function poolGrow);
- [MOX-002] Detect overflow from len=INT_MAX call to XML_Parse;
- [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.
