Deserialization of Untrusted Data Affecting python3-numpy-f2py package, versions <1:1.14.3-9.el8
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

CVE-2019-6446 (opens in a new tab)How to fix?
Upgrade RHEL:8 python3-numpy-f2py to version 1:1.14.3-9.el8 or higher.
This issue was patched in RHSA-2019:3704.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python3-numpy-f2py package and not the python3-numpy-f2py package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
An issue was discovered in NumPy before 1.16.3. 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.
