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. +--- + Makefile.am | 18 ++++++++++++++++++ + parser.c | 18 ++++++++++-------- + result/errors10/781205.xml | 0 + result/errors10/781205.xml.err | 21 +++++++++++++++++++++ + result/errors10/781361.xml | 0 + result/errors10/781361.xml.err | 13 +++++++++++++ + result/valid/766956.xml | 0 + result/valid/766956.xml.err | 9 +++++++++ + result/valid/766956.xml.err.rdr | 10 ++++++++++ + runtest.c | 3 +++ + test/errors10/781205.xml | 3 +++ + test/errors10/781361.xml | 3 +++ + test/valid/766956.xml | 2 ++ + test/valid/dtds/766956.dtd | 2 ++ + 14 files changed, 94 insertions(+), 8 deletions(-) + create mode 100644 result/errors10/781205.xml + create mode 100644 result/errors10/781205.xml.err + create mode 100644 result/errors10/781361.xml + create mode 100644 result/errors10/781361.xml.err + create mode 100644 result/valid/766956.xml + create mode 100644 result/valid/766956.xml.err + create mode 100644 result/valid/766956.xml.err.rdr + create mode 100644 test/errors10/781205.xml + create mode 100644 test/errors10/781361.xml + create mode 100644 test/valid/766956.xml + create mode 100644 test/valid/dtds/766956.dtd + +diff --git a/Makefile.am b/Makefile.am +index 6fc8ffa..10e716a 100644 +--- a/Makefile.am ++++ b/Makefile.am +@@ -427,6 +427,24 @@ Errtests : xmllint$(EXEEXT) + if [ -n "$$log" ] ; then echo $$name result ; echo "$$log" ; fi ; \ + rm result.$$name error.$$name ; \ + fi ; fi ; done) ++ @echo "## Error cases regression tests (old 1.0)" ++ -@(for i in $(srcdir)/test/errors10/*.xml ; do \ ++ name=`basename $$i`; \ ++ if [ ! -d $$i ] ; then \ ++ if [ ! -f $(srcdir)/result/errors10/$$name ] ; then \ ++ echo New test file $$name ; \ ++ $(CHECKER) $(top_builddir)/xmllint --oldxml10 $$i \ ++ 2> $(srcdir)/result/errors10/$$name.err \ ++ > $(srcdir)/result/errors10/$$name ; \ ++ grep "MORY ALLO" .memdump | grep -v "MEMORY ALLOCATED : 0"; \ ++ else \ ++ log=`$(CHECKER) $(top_builddir)/xmllint --oldxml10 $$i 2> error.$$name > result.$$name ; \ ++ grep "MORY ALLO" .memdump | grep -v "MEMORY ALLOCATED : 0"; \ ++ diff $(srcdir)/result/errors10/$$name result.$$name ; \ ++ diff $(srcdir)/result/errors10/$$name.err error.$$name` ; \ ++ if [ -n "$$log" ] ; then echo $$name result ; echo "$$log" ; fi ; \ ++ rm result.$$name error.$$name ; \ ++ fi ; fi ; done) + @echo "## Error cases stream regression tests" + -@(for i in $(srcdir)/test/errors/*.xml ; do \ + name=`basename $$i`; \ +diff --git a/parser.c b/parser.c +index df2efa5..a175ac4 100644 +--- a/parser.c ++++ b/parser.c +@@ -2121,7 +2121,6 @@ static void xmlGROW (xmlParserCtxtPtr ctxt) { + ctxt->input->line++; ctxt->input->col = 1; \ + } else ctxt->input->col++; \ + ctxt->input->cur += l; \ +- if (*ctxt->input->cur == '%') xmlParserHandlePEReference(ctxt); \ + } while (0) + + #define CUR_CHAR(l) xmlCurrentChar(ctxt, &l) +@@ -3412,13 +3411,6 @@ xmlParseNameComplex(xmlParserCtxtPtr ctxt) { + len += l; + NEXTL(l); + c = CUR_CHAR(l); +- if (c == 0) { +- count = 0; +- GROW; +- if (ctxt->instate == XML_PARSER_EOF) +- return(NULL); +- c = CUR_CHAR(l); +- } + } + } + if ((len > XML_MAX_NAME_LENGTH) && +@@ -3426,6 +3418,16 @@ xmlParseNameComplex(xmlParserCtxtPtr ctxt) { + xmlFatalErr(ctxt, XML_ERR_NAME_TOO_LONG, "Name"); + return(NULL); + } ++ if (ctxt->input->cur - ctxt->input->base < len) { ++ /* ++ * There were a couple of bugs where PERefs lead to to a change ++ * of the buffer.
