CVE-2020-16122

HIGH

PackageKit - Improper Privilege Management via APT Backend

Title source: llm
STIX 2.1

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.
