Firebird allows remote connections to the administrative account without verifying credentials.
| Package | dev-db/firebird on all architectures |
|---|---|
| Affected versions | < 2.0.3.12981.0-r6 |
| Unaffected versions | >= 2.0.3.12981.0-r6 |
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:
# 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.
