Hi Daniel,
The fix for the CVE-2014-0191 broke the --postvalid option. In that case, DTDs
are not loaded even though requested on the command line. This was the
CVE-2014-0191 patch:
https://git.gnome.org/browse/libxml2/commit/?id=9cd1c3cfbd32655d60572c0a413e017260c854df
With --postvalid specified on the command line, the XML_PARSE_DTDVALID is not
set in ctxt->options; instead, XML_PARSE_DTDLOAD is set). Same goes for the
other options that set XML_PARSE_DTDLOAD, --dtdvalid and --dtdvalidfpi.
Patch attached.
Regards,
Alexey.
