CVE-2019-6446: Fedoraproject Fedora

Critical severity, CVSS 9.8. EPSS: 17.5% chance of exploitation in the next 30 days.

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.

Affected products

• Fedoraproject Fedora: version 30 only
• Numpy Numpy: up to and including 1.16.0
