Vulnerability Title
aptdaemon allows unprivileged users to test for the presence of local files via the transaction Locale property
Source: CVE Program / CVE List V5
Vulnerability Description
There is no input validation on the Locale property in an apt transaction. An unprivileged user can supply a full path to a writable directory, which lets aptd read a file as root. Having a symlink in place results in an error message if the file exists, and no error otherwise. This way an unprivileged user can check for the existence of any files on the system as root.
