CVE-2020-16122
Publication date 13 June 2020
Last updated 24 July 2024
Ubuntu priority
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.
