Arch Linux Security Advisory ASA-202102-8
=========================================

Severity: High
Date : 2021-02-06
CVE-ID : CVE-2019-25016
Package : opendoas
Type : privilege escalation
Remote : No
Link :   https://security.archlinux.org/AVG-1504

Summary
=======

The package opendoas before version 6.8.1-2 is vulnerable to privilege
escalation.

Resolution
==========

Upgrade to 6.8.1-2.

# pacman -Syu "opendoas>=6.8.1-2"

The problem has been fixed upstream in version 6.8.1.

Workaround
==========

None.

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

A security issue has been found in OpenDoas before 6.8.1, where rules
that allowed the user to execute any command would inherit the
executing user's PATH instead of resetting it to a default PATH. Rules
that limit the user to execute only a specific command are not affected
by this and are only executed from the default PATH and with the PATH
environment variable set to the safe default.

Impact
======

A local user might be able to escalate privileges.
