GLSA-200805-06 : Firebird: Data disclosure

This script is Copyright (C) 2008-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200805-06
(Firebird: Data disclosure)

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.

Solution :

All Firebird users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=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.

Risk factor :

Medium / CVSS Base Score : 5.0
(CVSS2#AV:N/AC:L/Au:N/C:P/I:N/A:N)
