Subject: bug#8427: [SECURITY] sql.el -- comint process passwords are leaked to ps(1) listing
Date: Tue, 05 Apr 2011 14:27:03 +0300

Package: emacs
Version: 23.2+1-7
Severity: serious
Tags: security

There is a big security problem with sql.el:

    M-x sql-mysql
    <Fill in the connection details: user, password ...>

At command line, anyone in multi-user environment can dig out the
passwords:

   $ ps -ef -o user,pid,args | grep mysql       # ps(1) under SUN/Solaris
   foo  9599 /usr/local/bin/mysql --user=foo --password=123456 --host=db.example.com
   bar  3732 /usr/local/bin/mysql --user=bar --password=abcdef --host=db.example.com

P.S mysql(1) mentions that you can set database options in ~/.my.cnf file.

MySQL case, there is in manual page:
