Bacula: Information disclosure — GLSA 200807-10

A vulnerability in Bacula may allow local attackers to obtain sensitive information.

Affected Packages

app-backup/bacula on all architectures
Affected versions < 2.4.1
Unaffected versions >= 2.4.1

Background

Bacula is a network based backup suite.

Description

Matthijs Kooijman reported that the "make_catalog_backup" script uses the MySQL password as a command line argument when invoking other programs.

Impact

A local attacker could list the processes on the local machine when the script is running to obtain the MySQL password. Note: The password could also be disclosed via network sniffing attacks when the script fails, in which case it would be sent via cleartext e-mail.

Workaround

There is no known workaround at this time.

Resolution

A warning about this issue has been added in version 2.4.1, but the issue is still unfixed. We advise not to use the make_catalog_backup script, but to put all MySQL parameters into a dedicated file readable only by the user running Bacula.
