YaqlYamlLoader inherits from YamlLoader

[Kirill Zaitsev]

YaqlYamlLoader inherits from YamlLoader, meaning that it is possible to use extended unsafe tags in yaml files http://pyyaml.org/wiki/PyYAMLDocumentation#YAMLtagsandPythontypes

Both dashboard, engine/api seem to be vulnerable.

Patch for the murano-dashboard

[Kirill Zaitsev (kzaitsev)]

Confirmed for dashboard for mitaka, liberty and kilo

[Tristan Cacqueray (tristan-cacqueray)]

Note that kilo isn't security supported anymore as it is eol. Otherwise the change looks good to me.

Indeed, seems that we in murano missed EOL for kilo, gotta catch up with that. Also — http://releases.openstack.org needs to be updated as it still says, that kilo is security supported.

Patches seem to work for me, but I would like to see reviews from other Cores of the project, preferably from Stan Lagun, to verify, that these patches do not accidentally break existing functionality

[Kirill Zaitsev (kzaitsev)]

Stan pointed out, that we should also inherit from SafeConstructor instead of Coustructor, gotta add that to the patches to murano repository

[Stan Lagun (slagun)]

Looks good to me

    Inherit custom yaml Loader from yaml.SafeLoader

    Before this patch yaql-enabled yaml Loader was inherited from yaml.Loader, that
    potentially allows creating arbitrary python objects from specifically
    formatted yaml tags. This could have happened whenever UI definitions of
    the package were processed.
    With this change yaql yaml-Loader no longer allows creating custom python objects.

    Use SafeLoader to load yaml files

    Before this patch yaml.Loader was used by the engine to create custom
    yaql-enabled yaml loader. It is unsafe do to so, because yaml.Loader is
    capable of creating custom python objects from specifically constructed
    yaml files.
    After this patch all yaml load operations are performed with safe
    loaders instead.
    Also uses SafeConstructor instead of Constructor.
