All supported architectures
Firebird allows remote connections to the administrative account without
Firebird is a multi-platform, open source relational database.
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.
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).
There is no known workaround at this time.
All Firebird users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-db/firebird-126.96.36.19981.0-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.
