Nikolai Weibull c64d4efb 2018-10-13T00:12:12 Remove redefined starts and defines inside include elements 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.
Nikolai Weibull 46da8fc5 2018-10-12T23:46:24 Allow choice within choice in nameClass in RELAX NG 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.
Nikolai Weibull 4338c310 2018-10-12T22:30:26 Look inside divs for starts and defines inside include 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.
Nick Wellnhofer 123234f2 2018-09-11T14:52:07 Free input buffer in xmlHaltParser This avoids miscalculation of available bytes. Thanks to Yunho Kim for the report. Closes: #26
Nick Wellnhofer 72182550 2017-11-04T15:38:58 Add test for ICU flush and pivot buffer
Nick Wellnhofer 5af594d8 2017-10-07T14:54:45 Fix comparison of nodesets to strings 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. Reported by Aleksei on the mailing list: https://mail.gnome.org/archives/xml/2017-September/msg00016.html
Nick Wellnhofer 69936b12 2017-08-30T14:16:01 Revert "Print error messages for truncated UTF-8 sequences" 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.
Nick Wellnhofer 899a5d9f 2017-07-25T14:59:49 Detect infinite recursion in parameter entities 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.
Nick Wellnhofer 872fea94 2017-06-19T00:24:12 Get rid of "blanks wrapper" for parameter entities 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.
Nick Wellnhofer 24246c76 2017-06-20T12:56:36 Fix xmlHaltParser 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.
Nick Wellnhofer 8bbe4508 2017-06-17T16:15:09 Spelling and grammar fixes Fixes bug 743172, bug 743489, bug 769632, bug 782400 and a few other misspellings.
Nick Wellnhofer 5f440d8c 2017-06-12T14:32:34 Rework entity boundary checks 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.
Nick Wellnhofer dbaab1f3 2017-06-16T21:38:57 Test SAX2 callbacks with entity substitution This detects regressions like bug 760367.
Nick Wellnhofer 67f9f9d6 2017-06-12T19:25:01 Misc fixes for 'make tests' - 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
Nick Wellnhofer 0b2d5c48 2017-06-12T19:10:04 Initialize keepBlanks in HTML parser This caused failures in the HTML push tests but the fix required to change the expected output of the HTML SAX tests.
David Kilzer 85c112a0 2017-06-12T18:26:11 Add test cases for bug 758518 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.
Nick Wellnhofer 79c8a6b1 2017-06-10T17:01:27 Print error messages for truncated UTF-8 sequences 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.
Nick Wellnhofer 932cc989 2017-06-03T02:01:29 Fix buffer size checks in xmlSnprintfElementContent 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.
Nick Wellnhofer e2663054 2017-06-05T15:37:17 Fix handling of parameter-entity references 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.
Nick Wellnhofer 7482f41f 2017-06-01T22:00:19 Check for integer overflow in xmlXPathFormatNumber Check for overflow before casting double to int. Found with afl-fuzz and UBSan.
Nick Wellnhofer 855c19ef 2017-06-01T01:04:08 Avoid reparsing in xmlParseStartTag2 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.)
Nick Wellnhofer f4029cd4 2016-04-21T16:37:26 Check XPath exponents for overflow Avoid undefined behavior and wrong results with huge exponents. Found with afl-fuzz and UBSan.
Nick Wellnhofer a58331a6 2017-05-29T21:02:21 Check for overflow in xmlXPathIsPositionalPredicate Avoid undefined behavior when casting from double to int. Found with afl-fuzz and UBSan.
Nick Wellnhofer a851868a 2017-05-29T20:14:42 Parse small XPath numbers more accurately 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.
Nick Wellnhofer 4bebb030 2016-04-21T13:41:09 Rework XPath rounding functions 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.
Nick Wellnhofer 40f58521 2017-05-26T20:16:35 Fix axis traversal from attribute and namespace nodes 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.
Nick Wellnhofer 9ab01a27 2016-06-28T14:22:23 Fix XPointer paths beginning with range-to 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. Fixes CVE-2016-5131.
Nick Wellnhofer d8083bf7 2016-06-25T12:35:50 Fix NULL pointer deref in XPointer range-to - Check for errors after evaluating first operand. - Add sanity check for empty stack. Found with afl-fuzz.

Nick Wellnhofer 6eb0894a 2016-05-05T16:49:00 Fix memory leak with XPath namespace nodes Set hasNsNodes to 1 when adding namespace nodes via XP_TEST_HIT.
Nick Wellnhofer 82b73039 2016-04-30T17:53:10 Fix namespace axis traversal When the namespace axis is traversed in "toBool" mode, the traversal can exit early, before visiting all nodes. In this case, the XPath context still contains a non-NULL tmpNsList. This means that - the check when to start a new traversal was wrong and - the tmpNsList could be leaked. Fixes bug #750037 and, by accident, bug #756075: https://bugzilla.gnome.org/show_bug.cgi?id=750037 https://bugzilla.gnome.org/show_bug.cgi?id=756075

Nick Wellnhofer f39fd66e 2016-04-27T03:01:16 Fix namespace::node() XPath expression 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.

Nick Wellnhofer f6aaabce 2015-03-08T16:05:26 Allow attributes on descendant-or-self axis If the context node is an attribute, the attribute itself is on the descendant-or-self axis. The principal node type of this axis is element, so the only node test that can return the attribute is "node()". In other words, "@attr/descendant-or-self::node()" is equivalent to "@attr". This matches the behavior of Saxon-CE.

Daniel Veillard f933c898 2012-09-07T19:32:12 Keep non-significant blanks node in HTML parser For https://bugzilla.gnome.org/show_bug.cgi?id=681822 Regardless if the option HTML_PARSE_NOBLANKS is set or not, blank nodes are removed from a HTML document, for example: <html> <head> <title>This is a test.</title> </head> <body> <p>This is a test.</p> </body> </html> is read as: <html><head><title>This is a test.</title></head><body> <p>This is a test.</p> </body></html> This changes the default behaviour but the old behaviour is available as expected when using the parser flag HTML_PARSE_NOBLANKS Based on original patch from Igor Ignatyuk <igor_ignatiouk@hotmail.com> * HTMLparser.c: change various places in the parser where ignorable_space SAX callback was called without checking for the parser flag preference * xmllint.c: make sure we use the new flag even for HTML parsing * result/HTML/*: this modifies the output of a number of tests
Daniel Veillard e7bf892d 2012-07-30T20:09:25 Improve error reporting on parser errors The extra string was being dismissed when provided. * parser.c: handle bot case properly * result/: this changes a few error reports
Daniel Veillard 4629ee02 2012-07-23T14:15:40 Do not fetch external parsed entities Unless explicietely asked for when validating or replacing entities with their value. Problem pointed out by Tom Lane <tgl@redhat.com> * parser.c: do not load external parsed entities unless needed * test/errors/extparsedent.xml result/errors/extparsedent.xml*: add a regression test to avoid change of the behaviour in the future
Denis Pauk a0cd075d 2012-05-11T19:31:12 HTML parser error with <noscript> in the <head> For https://bugzilla.gnome.org/show_bug.cgi?id=615785 When the <noscript> is found, <head> is closed and a <body> element is created. The real <body id="xxx"> gets skipped over, so I can't see any of the body's attributes. Just don't close <head> when encountering a <noscript> Add a regression test too
Remi Gacogne 4609e6c9 2012-05-11T15:31:05 XSD: optional element in complex type extension For https://bugzilla.gnome.org/show_bug.cgi?id=609796 Libxml2 fails to validate an instance document against a schema if an element whose type is a complex extension of some base type with an optional child element and that child element is not specified in the instance document. For example, suppose I have some complex type BaseType that is defined to have one child element in a sequence group that has minOccurs set to 0
Denis Pauk 868d92da 2012-05-10T15:34:57 Add HTML parser support for HTML5 meta charset encoding declaration For https://bugzilla.gnome.org/show_bug.cgi?id=655218 http://www.w3.org/TR/2011/WD-html5-20110525/semantics.html#the-meta-element """ The charset attribute specifies the character encoding used by the document. This is a character encoding declaration. If the attribute is present in an XML document, its value must be an ASCII case-insensitive match for the string "UTF-8" (and the document is therefore forced to use UTF-8 as its encoding). """ However, while <meta http-equiv="Content-Type" content="text/html; charset=utf8"> works, <meta charset="utf8"> does not. While libxml2 HTML parser is not tuned for HTML5, this is a simple addition Also added a testcase
Daniel Veillard 77b77b13 2012-01-26T19:11:02 Fix SAX2 builder in case of undefined element namespaces Work as in XML-1.0 before namespaces, and use prefix:localname as the new element name (and no namespace of course) Also fix 3 cases in the regression tests where the prefix: was erroneously dropped in such case
Daniel Veillard cb3549e3 2011-11-11T11:25:07 Improve the error report on undefined REFs Use the tree node to provide the error context instead of the parser input which is not relevant anymore, based on a suggestion by François Delyon <f.delyon@satimage.fr>
Daniel Veillard 3c080d6d 2010-03-15T15:47:50 Don't give default HTML boolean attribute values in parser * HTMLparser.c: don't default value of HTML boolean attributes in the parser * SAX2.c: move this to SAX2 tree building backend * result/HTML/doc2.htm.sax result/HTML/doc3.htm.sax result/HTML/wired.html.sax: this changes a few HTML SAX regression tests

Daniel Veillard 1ba2aca3 2009-08-31T16:47:39 492317 Fix Relax-NG validation problems * relaxng.c xmlregexp.c: a subtle problem when checking for compileable content model, if using the same elements in cases of choices. Handled by adding a special flag to the regexp compilation to detect transitions with different atoms using same strings. * test/relaxng/492317* result/relaxng/492317*: add the test to the regression suite
