Debian 11 Evolution Data Server Key Update Risk Due to D-Bus File Deletion

An issue has been found in evolution-data-server, an evolution database
backend server.
A Flatpak application with D-Bus access to the addressbook service can
delete arbitrary files on the host, potentially including Flatpak override
files. This fix canonicalizes the file path before performing a prefix
comparison, ensuring that ../ sequences are resolved.


For Debian 11 bullseye, this problem has been fixed in version
3.38.3-1+deb11u3.

We recommend that you upgrade your evolution-data-server packages.
