Comment 2 Daniel Berrangé 2014-05-06 14:21:29 UTC

Cherry-picked to v1.1.3-maint branch

commit 46de45d079ae2622660fe147cf237ee617cc461c
Author: Daniel P. Berrange <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. Berrange <berrange>
    (cherry picked from commit d6b27d3e4c40946efa79e91d134616b41b1666c4)
