phpmyadmin -- information disclosure vulnerability

A phpMyAdmin security announcement reports:

By calling some scripts that are part of phpMyAdmin in an
unexpected way (especially scripts in the libraries
subdirectory), it is possible to trigger phpMyAdmin to
display a PHP error message which contains the full path
of the directory where phpMyAdmin is installed.
Mitigation factor: This path disclosure
is possible on servers where the recommended setting of
the PHP configuration directive
display_errors is set to on, which is against
the recommendations given in the PHP manual.
