Subject: [PATCH] libxslt: heap-use-after-free in xmlFreeID caused by `atype`
corruption
* include/libxml/tree.h:
(XML_ATTR_CLEAR_ATYPE): Add.
(XML_ATTR_GET_ATYPE): Add.
(XML_ATTR_SET_ATYPE): Add.
(XML_NODE_ADD_EXTRA): Add.
(XML_NODE_CLEAR_EXTRA): Add.
(XML_NODE_GET_EXTRA): Add.
(XML_NODE_SET_EXTRA): Add.
(XML_DOC_ADD_PROPERTIES): Add.
(XML_DOC_CLEAR_PROPERTIES): Add.
(XML_DOC_GET_PROPERTIES): Add.
(XML_DOC_SET_PROPERTIES): Add.
- Add macros for accessing fields with upper bits that may be set by
libxslt.
* HTMLparser.c:
(htmlNewDocNoDtD):
* SAX2.c:
(xmlSAX2StartDocument):
(xmlSAX2EndDocument):
* parser.c:
(xmlParseEntityDecl):
(xmlParseExternalSubset):
(xmlParseReference):
(xmlCtxtParseDtd):
* runxmlconf.c:
(xmlconfTestInvalid):
(xmlconfTestValid):
* tree.c:
(xmlNewDoc):
(xmlFreeProp):
(xmlNodeSetDoc):
(xmlSetNsProp):
(xmlDOMWrapAdoptBranch):
* valid.c:
(xmlFreeID):
(xmlAddIDInternal):
(xmlValidateAttributeValueInternal):
(xmlValidateOneAttribute):
(xmlValidateRef):
* xmlreader.c:
(xmlTextReaderStartElement):
(xmlTextReaderStartElementNs):
(xmlTextReaderValidateEntity):

(xmlTextReaderNext):
(xmlTextReaderIsEmptyElement):
(xmlTextReaderPreserve):
* xmlschemas.c:
(xmlSchemaPValAttrNodeID):
* xmlschemastypes.c:
(xmlSchemaValAtomicType):
- Adopt macros by renaming the struct fields, recompiling and fixing
compiler failures, then changing the struct field names back.
