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. References ========== [ 1 ] CVE-2008-1880 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1880 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200805-06.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
