makecatalogbackup in Bacula 2.2.5, and probably earlier, sends a MySQL password as a command line argument, and sometimes transmits cleartext e-mail containing this command line, which allows context-dependent attackers to obtain the password by listing the process and its arguments, or by sniffing the network.

The dumpresource function in dird/dirdconf.c in Bacula before 5.2.11 does not properly enforce ACL rules, which allows remote authenticated users to obtain resource dump information via unspecified vectors.

bacula 1.36.3 and earlier allows local users to modify or read sensitive files via symlink attacks on (1) the temporary file used by autoconf/randpass when openssl is not available, or (2) the mtx.[PID] temporary file in mtx-changer.in.
