CVE-2020-16122

Packagekit's apt backend lets user install untrusted local packages

State: Published
Severity: 8.2 High
Published: Nov 7, 2020
Updated: Sep 16, 2024
Reserved: Jul 29, 2020

Description

PackageKit's apt backend mistakenly treated all local debs as trusted. The apt security model is based on repository trust and not on the contents of individual files. On sites with configured PolicyKit rules this may allow users to install malicious packages.
