Description:
Matthijs Kooijman has reported a weakness in Bacula, which can be exploited by malicious, local users to disclose potentially sensitive information.
The weakness is caused due to the "make_catalog_backup" script using the MySQL password as command line argument when invoking other programs. This can be exploited to disclose the password via e.g. the "ps" command.
Note: In case of an error, the script may also send the MySQL password in an unencrypted email, which can be exploited to disclose the password via sniffing attacks.
Solution:
The vendor recommends passing the MySQL password via an environment variable or a secure file. Disable the email message notification.
Provided and/or discovered by:
Reported in a Debian bug by Matthijs Kooijman.
Changelog:
