The version of MySQL installed on the remote host is 5.5.x prior to 5.5.33. It is, therefore, potentially affected by a race condition in the post-installation script of the MySQL server package (mysql-server-5.5.postinst) that creates the configuration file ‘/etc/mysql/debian.cnf’ with world-readable permissions before restricting the permissions. This allows local users to read the file and obtain credentials for the privileged ‘debian-sys-maint’ user.
