Description Marian Rehak 2020-10-02 10:15:32 UTC

PackageKit incorrectly handled local deb packages. A local user could possibly use this issue to install untrusted packages, contrary to expectations.

Comment 3 Todd Cullum 2020-10-06 20:57:19 UTC

Statement:

PackageKit as shipped with Red Hat Enterprise Linux 6, 7, and 8 is not affected by this flaw because it uses a different backend, and the flaw is specific to the aptcc backend used for debian-based systems.
