The default configuration of logrotate on Debian GNU/Linux uses root
privileges to process files in directories that permit non-root write
access, which allows local users to conduct symlink and hard link attacks
by leveraging logrotate’s lack of support for untrusted directories, as
demonstrated by /var/log/postgresql/.
