Synopsis  
========

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  
==========

There is no known workaround at this time.

Resolution  
==========

All Joblib users should upgrade to the latest version:

  # emerge --sync  
  # emerge --ask --oneshot --verbose ">=dev-python/joblib-1.2.0"
