Arch Linux Security Advisory ASA-202107-39
=========================================
Severity: Medium
Date    : 2021-07-20
CVE-ID  : CVE-2021-32773
Package : racket
Type    : sandbox escape
Remote  : Yes
Link    : https://security.archlinux.org/AVG-2175

Summary
======
The package racket before version 8.2-1 is vulnerable to sandbox
escape.

Resolution
=========
Upgrade to 8.2-1.

# pacman -Syu "racket>=8.2-1"

The problem has been fixed upstream in version 8.2.

Workaround
=========
None.

Description
==========
In Racket versions prior to 8.2, code evaluated using the Racket
sandbox could cause system modules to incorrectly use attacker-created
modules instead of their intended dependencies. This could allow system
functions to be controlled by the attacker, giving access to facilities
intended to be restricted.

Impact
=====
Code executed in the Racket sandbox could escape its confinement
through attacker-created modules.
