* Upgrade libxml2 to 1a360c1c2ec950f478d55b31722ecf78f5698e97Haibo Huang2020-07-311-0/+8
| | | | | | | | | | | Also change upstream to github. This change moves away from stable release. Because we need CMakeLists.txt. It is not in any release yet. They are likely to release another stable version within this year. We can upgrade to that version when it is available. Bug: 157157503 Change-Id: If6f245dbabe36a114563d209c8e100b7e3083f20
* Check for integer overflow in xmlXPathFormatNumberNick Wellnhofer2017-06-012-0/+16
| | | | | | Check for overflow before casting double to int. Found with afl-fuzz and UBSan.
* Check XPath exponents for overflowNick Wellnhofer2017-05-311-0/+32
| | | | | | Avoid undefined behavior and wrong results with huge exponents. Found with afl-fuzz and UBSan.
* Parse small XPath numbers more accuratelyNick Wellnhofer2017-05-311-0/+8
| | | | | | | | | | | | | 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.
* Rework XPath rounding functionsNick Wellnhofer2017-05-311-0/+68
| | | | | | | | | 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.
* Don't recurse into OP_VALUEs in xmlXPathOptimizeExpressionNick Wellnhofer2016-04-271-0/+4
| | | | | | | | The ch1 slot of OP_VALUEs contains an invalid value. Ignore it. Fixes bug #760325: https://bugzilla.gnome.org/show_bug.cgi?id=760325
* Fix parsing of NCNames in XPathNick Wellnhofer2016-04-231-0/+4
| | | | | | | | | The NCName parser would allow any NameChar as start character. For example, the following XPath expressions would compile: self::-abc self::0abc self::.abc
