b8313b58 | 2023-12-26 21:59:08 | xpath: Rewrite substring-before and substring-after Don't use buffers. Check malloc failures. | |
|
608c65bb | 2023-01-18 15:15:41 | xpath: number('-') should return NaN Fixes https://gitlab.gnome.org/GNOME/libxslt/-/issues/81 | |
|
57b81c20 | 2022-03-05 18:20:29 | Normalize XPath strings in-place Simplify the code and fix a potential memory leak. Fixes #343. | |
|
30a6533e | 2019-03-08 12:15:17 | Fix float casts in xmlXPathSubstringFunction 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. | |
|
7482f41f | 2017-06-01 22:00:19 | Check for integer overflow in xmlXPathFormatNumber Check for overflow before casting double to int. Found with afl-fuzz and UBSan. | |
|
f4029cd4 | 2016-04-21 16:37:26 | Check XPath exponents for overflow Avoid undefined behavior and wrong results with huge exponents. Found with afl-fuzz and UBSan. | |

a851868a | 2017-05-29 20:14:42 | 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. | |
|
4bebb030 | 2016-04-21 13:41:09 | 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. | |
|
839689a9 | 2016-04-27 18:00:12 | Don't recurse into OP_VALUEs in xmlXPathOptimizeExpression The ch1 slot of OP_VALUEs contains an invalid value. Ignore it. Fixes bug #760325: https://bugzilla.gnome.org/show_bug.cgi?id=760325 | |

e2893903 | 2016-04-21 19:19:23 | Fix parsing of NCNames in XPath The NCName parser would allow any NameChar as start character. For example, the following XPath expressions would compile: self::-abc self::0abc self::.abc |
