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. - xmlParseAttValueCompl...
