FreeBSD's C library (libc) contains code for creating and accessing Berkeley DB 1.85 database files. Such databases are used extensively in FreeBSD for example, the system password files (/etc/passwd and /etc/master.passwd) are normally accessed via their database files (/etc/pwd.db and /etc/spwd.db). Some data structures used by the database interface code are not properly initialized when allocated.
