"This update for python-numpy fixes the following issue :

Security issue fixed :

CVE-2019-6446: Set allow_pickle to false by default to restrict
loading untrusted content (bsc#1122208). With this update we decrease
the possibility of allowing remote attackers to execute arbitrary code
by misusing numpy.load(). A warning during runtime will show-up when
the allow_pickle is not explicitly set.

NOTE: By applying this update the behavior of python-numpy changes,
which might break your application. In order to get the old behaviour
back, you have to explicitly set `allow_pickle` to True. Be aware that
this should only be done for trusted input, as loading untrusted input
might lead to arbitrary code execution.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
