The value is also assigned to $MLDBM::Serializer, which MLDBM requires the same way when it ties the table.\n\nA caller that lets an untrusted party influence either attribute, for example through a DSN fragment or a parameter that selects a storage backend, runs the file-scope code of whatever module the value names.\n\nFor example,\n\n    my $dsn = \"dbi:DBM:f_dir=/var/db;dbm_type=../../Untrusted.pm\"\n    my $dbh = DBI->connect( $dsn );\n\nNote that DBD::Gofer forwards connect attributes to the server side, and DBI::ProxyServer checks only that a DSN starts with a driver prefix."
