-Subject: [PATCH] Fix handling of parameter-entity references
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-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.
-
-- xmlParseAttValueComplex
-- xmlParseCharDataComplex
-- xmlParseCommentComplex
-- xmlParsePI
-- xmlParseCDSect
-
-Parameter-entity references are ignored outside the DTD.
-
-- xmlLoadEntityContent
-
-This function is only called from xmlStringLenDecodeEntities and
-entities are replaced in a separate step immediately after the function
-call.
-
-This bug could also be triggered with an internal subset and double
-entity expansion.
-
-This fixes bug 766956 initially reported by Wei Lei and independently by
-Chromium's ClusterFuzz, Hanno Böck, and Marco Grassi. Thanks to everyone
-involved.
-
-xmlParseNameComplex with XML_PARSE_OLD10
-========================================
-
-When parsing Names inside an expanded parameter entity with the
-XML_PARSE_OLD10 option, xmlParseNameComplex would call xmlGROW via the
-GROW macro if the input buffer was exhausted. At the end of the
-parameter entity's replacement text, this function would then call
-xmlPopInput which invalidated the input buffer.
-
-There should be no need to invoke GROW in this situation because the
-buffer is grown periodically every XML_PARSER_CHUNK_SIZE characters and,
-at least for UTF-8, in xmlCurrentChar. This also matches the code path
-executed when XML_PARSE_OLD10 is not set.
-
-This fixes bugs 781205 (CVE-2017-9049) and 781361 (CVE-2017-9050).
-Thanks to Marcel Böhme and Thuan Pham for the report.
-
-Additional hardening
-====================
-
-A separate check was added in xmlParseNameComplex to validate the
-buffer size.
