http://security.gentoo.org/

Severity:	normal
Title:	Babel: Remote code execution
Date:	08/04/2022
Bugs:	#786954
ID:	202208-03

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	Architecture(s)
dev-python/Babel	< 2.9.1	>= 2.9.1	All supported architectures

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"
