+Subject: [PATCH] dmidecode: Do not let --dump-bin overwrite an existing file
+
+Make sure that the file passed to option --dump-bin does not already
+exist. In practice, it is rather unlikely that an honest user would
+want to overwrite an existing dump file, while this possibility
+could be used by a rogue user to corrupt a system file.
+
