Rating: important
References: #1122208

Affected Products:
  • SUSE Linux Enterprise Point of Sale 11-SP3

An update that fixes one vulnerability is now available.

Description:

This update for python-numpy fixes the following issues:
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.
