Firebird SYSDBA unauthorized access
|firebird-sysdba-unauth-access (42299)||High Risk|
The Gentoo Linux Firebird init script could allow a remote attacker to obtain unauthorized access, caused by the ISC_PASSWORD environment variable being set when initially connecting to Firebird. By then initiating a client connection to the SYSDBA user account without supplying a password, a remote attacker could exploit this vulnerability to gain unauthorized access to the database.
Refer to GLSA 200805-06 for patch, upgrade or suggested workaround information. See References.
