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 lt; 2.0.3.12981.0-r6 gt;= 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 "gt;=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.

References
==========
