Subject: Re: CVE request: out-of-bounds read parsing an XML in libxml2 using recover mode

Use CVE-2016-4483 for this buffer over-read issue.

(As far as we can tell, xmlsave.c is not specific to the xmllint program, e.g.,

  libxml2_la_SOURCES = SAX.c entities.c encoding.c error.c parserInternals.c  \
  ...
                  xmlwriter.c legacy.c chvalid.c pattern.c xmlsave.c \

in the Makefile.in file.)
