Debian 11 PackageKit Important Privilege Escalation DLA-4545-1

Maik Schaefer discovered that a TOCTOU race condition in PackageKit (a
package management service over a DBus interface) could result in local
privilege escalation.


For Debian 11 bullseye, this problem has been fixed in version
1.2.2-2+deb11u1.

We recommend that you upgrade your packagekit packages.
