The remote host is missing updates announced in advisory GLSA 200805-06.

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. http://www.securityspace.com/smysecure/catid.html?in=GLSA%20200805-06 http://bugs.gentoo.org/show_bug.cgi?id=216158

Firebird allows remote connections to the administrative account without verifying credentials.
