[Pkg-dspam-misc] Bug#448519: libdspam7-drv-mysql: cron job may disclose dspam database password to users

[Tobias Gruetzmacher]

Package: libdspam7-drv-mysql
Version: 3.6.8-5
Severity: grave
Tags: security
Justification: user security hole

The cron job in /etc/cron.daily/libdspam7-drv-mysql calls mysql like
this:

   /usr/bin/mysql --user=$MYSQL_USER --password=$MYSQL_PASS

This makes the database password of the dspam database user visible in
the command line, so users may see it using ps. A malicious local user
can use this to connect to the dspam databse and read all recent mail of
dspam users. This bug is easily fixed my using a config file or
environment variable to pass the password to mysql.
