"Two vulnerabilities have been discovered in packagekit, a package
management service.

CVE-2020-16121

Vaisha Bernard discovered that PackageKit incorrectly handled certain
methods. A local attacker could use this issue to learn the MIME type
of any file on the system.

CVE-2020-16122

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

For Debian 9 stretch, these problems have been fixed in version
1.1.5-2+deb9u2.

We recommend that you upgrade your packagekit packages.
