A vulnerability has been found in Joblib which allows for arbitrary code
execution.

Background
==========

Joblib is a set of tools to provide lightweight pipelining in Python. In
particular:

1. transparent disk-caching of functions and lazy re-evaluation (memoize
pattern)
2. easy simple parallel computing

Joblib is optimized to be fast and robust on large data in particular
and has specific optimizations for numpy arrays.

Affected packages
=================

Package            Vulnerable    Unaffected
-----------------  ------------  ------------
dev-python/joblib  < 1.2.0       >= 1.2.0

Description
===========

A vulnerability has been discovered in Joblib. Please review the CVE
identifier referenced below for details.

Impact
======

Joblib is vulnerable to arbitrary code execution via the pre_dispatch
flag in Parallel() class due to the eval() statement.

Workaround
