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"
References
