Previously, test/relaxng/ambig_name-class.xml would fail to validate
for a simple reason -- interleave within "open-name-class" context
is supposed to be fine with whatever else is pending the consumption,
since effectively, it's unrelated from a higher parsing perspective.

Consolidate code paths evaluating XPath predicates and filters.
Don't push context node on stack when evaluating predicates. I have no
idea why this was done. It seems completely useless and trying to pop
the context node from a corrupted stack has already caused security
issues.
Filter nodesets in-place and don't create node sets with NULL gaps which
allows to simplify merging a great deal. Simply move matched nodes
backward and create a compact node set.
Merge xmlXPathCompOpEvalPositionalPredicate into
xmlXPathCompOpEvalPredicate.
Rewrite conversion of double to int in xmlXPathSubstringFunction, adding
range checks to avoid undefined behavior. Make sure to add start and
length as floating-point numbers before converting to int. Fix a bug
when rounding negative start indices.
Remove unneeded calls to xmlXPathIs{Inf,NaN} and rely on IEEE math
instead. Avoid computing the string length. xmlUTF8Strsub works as
expected if the length of the requested substring exceeds the input.
Found with libFuzzer and UBSan.
When including a grammar from another grammar, we need to make sure that any
redefines of starts and includes that that grammar does inside any of its
include elements are also removed.
The pattern nameClass allows for nested choice elements, for example
<name>
<choice>
<choice>
<name>a</name>
<name>b</name>
</choice>
<name>c</name>
</choice>
</name>
which is semantically equivalent to
<name>
<choice>
<name>a</name>
<name>b</name>
<name>c</name>
</choice>
</name>
The old code didn’t handle this correctly, as it never expected a choice inside
another choice. This patch fixes this by flattening any nested choices.
This pattern of nested choice elements comes up in RELAX NG simplification,
where all choice elements are rewritten in this nested manner, see section 4.12
of the RELAX NG specification.
RELAX NG allows for div elements inside of include elements. We need to look
inside those div elements for start and define elements that may be redefining
start and define elements in the included grammar.
Fix two bugs in xmlXPathNodeValHash which could lead to errors when
comparing nodesets to strings:
- Only use contents of text nodes to compute the hash for element nodes.
Comments, PIs, and other node types don't affect the string-value and
must be ignored.
- Reset `string` to NULL for node types other than text.

This reverts commit 79c8a6b which caused a serious regression in
streaming mode.
Also reverts part of commit 52ceced "Fix infinite loops with push
parser in recovery mode".
Fixes bug 786554.
When expanding a parameter entity in a DTD, infinite recursion could
lead to an infinite loop or memory exhaustion.
Thanks to Wei Lei for the first of many reports.
Fixes bug 759579.
Now that replacement of parameter entities goes exclusively through
xmlSkipBlankChars, we can account for the surrounding space characters
there and remove the "blanks wrapper" hack.
Pop all extra input streams before resetting the input. Otherwise,
a call to xmlPopInput could make input available again.
Also set input->end to input->cur.
Changes the test output for some error tests. Unfortunately, some
fuzzed test cases were added to the test suite without manual cleanup.
This makes it almost impossible to review the impact of later changes
on the test output.
Make sure to finish all entities in the internal subset. Nevertheless,
readd a sanity check in xmlParseStartTag2 that was lost in my previous
commit. Also add a sanity check in xmlPopInput. Popping an input
unexpectedly was the source of many recent memory bugs. The check
doesn't mitigate such issues but helps with diagnosis.
Always base entity boundary checks on the input ID, not the input
pointer. The pointer could have been reallocated to the old address.
Always throw a well-formedness error if a boundary check fails. In a
few places, a validity error was thrown.
Fix a few error codes and improve indentation.
- Silence test output.
- Clean up after doc/examples tests.
- Adjust expected output for script tests.
- Add missing results for relaxng/pattern3
There are still two test failures I can't comment on:
- regexp/bug316338
- schemas/any4_0
test/HTML/758518-entity.html exposed a bug in pushParseTest() in
runtest.c which assumed that an input file was at least 4 bytes long.
That test case is only 3 bytes, so we now take the minimum of 4 bytes
or the length of the test input. We also now use 'chunkSize' in place
of the hard-coded value '1024' later in the function.
Before, truncated UTF-8 sequences at the end of a file were treated as
EOF. Create an error message containing the offending bytes.
xmlStringCurrentChar would also print characters from the input stream,
not the string it's working on.
xmlSnprintfElementContent failed to correctly check the available
buffer space in two locations.
Fixes bug 781333 (CVE-2017-9047) and bug 781701 (CVE-2017-9048).
Thanks to Marcel Böhme and Thuan Pham for the report.
There were two bugs where parameter-entity references could lead to an
unexpected change of the input buffer in xmlParseNameComplex and
xmlDictLookup being called with an invalid pointer.
Percent sign in DTD Names
=========================
The NEXTL macro used to call xmlParserHandlePEReference. When parsing
"complex" names inside the DTD, this could result in entity expansion
which created a new input buffer. The fix is to simply remove the call
to xmlParserHandlePEReference from the NEXTL macro. This is safe because
no users of the macro require expansion of parameter entities.
- xmlParseNameComplex
- xmlParseNCNameComplex
- xmlParseNmtoken
The percent sign is not allowed in names, which are grammatical tokens.
- xmlParseEntityValue
Parameter-entity references in entity values are expanded but this
happens in a separate step in this function.
- xmlParseSystemLiteral
Parameter-entity references are ignored in the system literal.
- xmlParseAttValueComplex
- xmlParseCharDataComplex
- xmlParseCommentComplex
- xmlParsePI
- xmlParseCDSect
Parameter-entity references are ignored outside the DTD.
- xmlLoadEntityContent
This function is only called from xmlStringLenDecodeEntities and
entities are replaced in a separate step immediately after the function
call.
This bug could also be triggered with an internal subset and double
entity expansion.
This fixes bug 766956 initially reported by Wei Lei and independently by
Chromium's ClusterFuzz, Hanno Böck, and Marco Grassi. Thanks to everyone
involved.
xmlParseNameComplex with XML_PARSE_OLD10
========================================
When parsing Names inside an expanded parameter entity with the
XML_PARSE_OLD10 option, xmlParseNameComplex would call xmlGROW via the
GROW macro if the input buffer was exhausted. At the end of the
parameter entity's replacement text, this function would then call
xmlPopInput which invalidated the input buffer.
There should be no need to invoke GROW in this situation because the
buffer is grown periodically every XML_PARSER_CHUNK_SIZE characters and,
at least for UTF-8, in xmlCurrentChar. This also matches the code path
executed when XML_PARSE_OLD10 is not set.
This fixes bugs 781205 (CVE-2017-9049) and 781361 (CVE-2017-9050).
Thanks to Marcel Böhme and Thuan Pham for the report.
Additional hardening
====================
A separate check was added in xmlParseNameComplex to validate the
buffer size.
The code in xmlParseStartTag2 must handle the case that the input
buffer was grown and reallocated which can invalidate pointers to
attribute values. Before, this was handled by detecting changes of
the input buffer "base" pointer and, in case of a change, jumping
back to the beginning of the function and reparsing the start tag.
The major problem of this approach is that whether an input buffer is
reallocated is nondeterministic, resulting in seemingly random test
failures. See the mailing list thread "runtest mystery bug: name2.xml
error case regression test" from 2012, for example.
If a reallocation was detected, the code also made no attempts to
continue parsing in case of errors which makes a difference in
the lax "recover" mode.
Now we store the current input buffer "base" pointer for each (not
separately allocated) attribute in the namespace URI field, which isn't
used until later. After the whole start tag was parsed, the pointers
to the attribute values are reconstructed using the offset between the
new and the old input buffer. This relies on arithmetic on dangling
pointers which is technically undefined behavior. But it seems like
the easiest and most efficient fix and a similar approach is used in
xmlParserInputGrow.
This changes the error output of several tests, typically making it
more verbose because we try harder to continue parsing in case of
errors.
(Another possible solution is to check not only the "base" pointer
but the size of the input buffer as well. But this would result in
even more reparsing.)
Don't count leading zeros towards the fraction size limit. This allows
to parse numbers like
0.0000000000000000000000000000000000000000000000000000000001
which is the only standard-conformant way to represent such numbers, as
scientific notation isn't allowed in XPath 1.0. (It is allowed in XPath
2.0 and in libxml2 as an extension, though.)
Overall accuracy is still bad, see bug 783238.
Use the C library's floor and ceil functions. The old code was overly
complicated for no apparent reason and could result in undefined
behavior when handling NaNs (found with afl-fuzz and UBSan).
Fix wrong comment in xmlXPathRoundFunction. The implementation was
already following the spec and rounding half up.
When traversing the "preceding" axis from an attribute node, we must
first go up to the attribute's containing element. Otherwise, text
children of other attributes could be returned. This made it possible
to hit a code path in xmlXPathNextAncestor which contained another bug:
The attribute node was initialized with the context node instead of the
current node. Normally, this code path is only hit via
xmlXPathNextAncestorOrSelf in which case the current and context node
are the same.
The combination of the two bugs could result in an infinite loop, found
with libFuzzer.
Traversing the "following" and the "preceding" axis from namespace nodes
should be handled similarly. This wasn't supported at all previously.
The old code would invoke the broken xmlXPtrRangeToFunction. range-to
isn't really a function but a special kind of location step. Remove
this function and always handle range-to in the XPath code.
The old xmlXPtrRangeToFunction could also be abused to trigger a
use-after-free error with the potential for remote code execution.
Found with afl-fuzz.

Make sure that xmlXPathNodeSetAddNs is called for namespace nodes when
matched with a namespace::node() step. This correctly sets the parent
of namespace nodes. Note that xmlXPathNodeSetAddNs must only be called
if working on the namespace axis. Otherwise, the context node is not
the parent of the namespace node and the standard XP_TEST_HIT macro
must be invoked. This explains the errors in the C14N tests that the
old TODO comment mentioned.
The NCName parser would allow any NameChar as start character. For
example, the following XPath expressions would compile:
self::-abc
self::0abc
self::.abc

so the only node test that can return the attribute is "node()". In other

Restructured the validation process.
Restructured and expanded parsing of <attributeGroup>.
Added initial handing of xsi:type.
Advanced handling of xsi:nil (should work now for simple types).
Added construction of schemata using xsi:schemaLocation and
xsi:noNamespaceSchemaLocation; this is not enabled, since
no corresponding API exists yet.
Moved the content model to complex type components.
Resolution of types for attributes will look for simple types
only (incl. all the built-in simple types).
Extended parsing of 'anyAttribute'.
Fixed content-type type for complex types if derived from

schemas.
Fixed a bug which reported attributes as invalid on
elements declarations with the built-in type 'anyType'.
Added "lax" validation of the content of elements of type
'anyType'.
Fixed: element declarations with the same name were treated
as duplicate if located in the subtree of <choice> -> <sequence>.
