FreeBSD Security Advisory – Some data structures used by the database interface code are not properly initialized when allocated. Programs using the db(3) interface to create Berkeley database files may “leak” sensitive information into database files. If those files can be read by other users, this may result in the disclosure of sensitive information such as login credentials.
