Synopsis
========

A vulnerability in Babel could result in remote code execution.

Background
==========

Babel is a collection of tools for internationalizing Python
applications.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-python/Babel           < 2.9.1                      >= 2.9.1 

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

Babel does not properly restrict which sources a locale can be loaded
from. If Babel loads an attacker-controlled .dat file, arbitrary code
execution can be achieved via unsafe Pickle deserialization.

Impact
======

An attacker with filesystem access and control over the locales Babel loads can achieve code execution.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Babel users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-python/Babel-2.9.1"
