+Subject: [PATCH] lib/DBD/File.pm: fix CVE-2014-10401
+
+Dig into the root cause of RT#99508 - which resulted in CVE-2014-10401 - and
+figure out that DBI->parse_dsn is the wrong helper to parse our attributes in
+DSN, since in DBD::dr::connect only the "dbname" remains from DSN which causes
+parse_dsn to bailout.
+
+Parsing on our own similar to parse_dsn shows the way out.
