Arch Linux Security Advisory ASA-202009-11
==========================================

Severity: High
Date    : 2020-09-26
CVE-ID  : CVE-2020-14370
Package : podman
Type    : information disclosure
Remote  : Yes
Link    : https://security.archlinux.org/AVG-1233

Summary
=======

The package podman before version 2.1.0-1 is vulnerable to information
disclosure.

Resolution
==========

Upgrade to 2.1.0-1.

# pacman -Syu "podman>=2.1.0-1"

The problem has been fixed upstream in version 2.1.0.

Workaround
==========

None.

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

A flaw was discovered in Podman before upstream version 2.0.5. When
using the deprecated Varlink API or the Docker-compatible REST API, if
multiple containers are created in a short duration, the environment
variables from the first containers will get leaked into subsequent
containers. An attacker who has control over those subsequent
containers may get access to secrets shared with previous containers
through environment variables.

Impact
======

A local privileged user can potentially view secrets in environment
variables.
