| Name | CVE-2019-6446 |
| Description | An issue was discovered in NumPy 1.16.0 and earlier. It uses the pickle Python module unsafely, which allows remote attackers to execute arbitrary code via a crafted serialized object, as demonstrated by a numpy.load call. NOTE: third parties dispute this issue because it is a behavior that might have legitimate applications in (for example) loading serialized Python object arrays from trusted and authenticated sources |

Notes
[jessie] - python-numpy <no-dsa> (Minor issue)
https://github.com/numpy/numpy/issues/12759
For upstream this works as intended and is documented.
https://github.com/numpy/numpy/commit/a2bd3a7eabfe053d6d16a2130fdcad9e5211f6bb
added support to disable use of picke in load/save, marking that as the fixed
version. The use of that is at the discretion of anyone using numpy
