Synopsis

========

 

Firebird allows remote connections to the administrative account

without verifying credentials.

 

Background

==========

 

Firebird is a multi-platform, open source relational database.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 dev-db/firebird < 2.0.3.12981.0-r6 >= 2.0.3.12981.0-r6

 

Description

===========

 

Viesturs reported that the default configuration for Gentoo's init

script ("/etc/conf.d/firebird") sets the "ISC_PASSWORD" environment

variable when starting Firebird. It will be used when no password is

supplied by a client connecting as the "SYSDBA" user.

 

Impact

======

 

A remote attacker can authenticate as the "SYSDBA" user without

providing the credentials, resulting in complete disclosure of all

databases except for the user and password database (security2.fdb).

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All Firebird users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot -v ">=dev-db/firebird-2.0.3.12981.0-r6"

 

Note: /etc/conf.d is protected by Portage as a configuration directory.

Do not forget to use "etc-update" or "dispatch-conf" to overwrite the

"firebird" configuration file, and then restart Firebird.
