Title: Firebird: Data disclosure
Date: May 09, 2008
Bugs: #216158
ID: 200805-06

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.
