commit d6b27d3e4c40946efa79e91d134616b41b1666c4 Author: Daniel P. Berrange Date: Tue Apr 15 11:20:29 2014 +0100 LSN-2014-0003: Don't expand entities when parsing XML If the XML_PARSE_NOENT flag is passed to libxml2, then any entities in the input document will be fully expanded. This allows the user to read arbitrary files on the host machine by creating an entity pointing to a local file. Removing the XML_PARSE_NOENT flag means that any entities are left unchanged by the parser, or expanded to "" by the XPath APIs. Signed-off-by: Daniel P.
