SUSE Security Update: Security update for python-numpy

______________________________________________________________________________

Announcement ID:   SUSE-SU-2019:13977-1
Rating:            important
References:        #1122208
Cross-References:  CVE-2019-6446
Affected Products:
                   SUSE Linux Enterprise Point of Sale 11-SP3
                   SUSE Linux Enterprise Debuginfo 11-SP4
______________________________________________________________________________

An update that fixes one vulnerability is now available.

Description:

This update for python-numpy fixes the following issues:
Security issue fixed:

  o 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.

methods like YaST online_update or "zypper patch".
