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. |
