The TNS Listener, as used in Oracle Database 11g 11.1.0.7, 11.2.0.2, and 11.2.0.3, and 10g 10.2.0.3, 10.2.0.4, and 10.2.0.5, as used in Oracle Fusion Middleware, Enterprise Manager, E-Business Suite, and possibly other products, allows remote attackers to execute arbitrary database commands by performing a remote registration of a database (1) instance or (2) service name that already exists, then conducting a man-in-the-middle (MITM) attack to hijack database connections, aka "TNS Poison."

Multiple unspecified vulnerabilities in Oracle Database 9.0.1.5+, 9.2.0.8, 9.2.0.8DV, 10.1.0.5, and 10.2.0.3 have unknown impact and remote attack vectors, related to (1) the Export component (DB02), (2) Oracle Text (DB04), (3) Oracle Text (DB05), (4) Spatial component (DB07), and (5) Advanced Security Option (DB19).

Unspecified vulnerability in the Oracle Database Vault component in Oracle Database 9.2.0.8DV and 10.2.0.3 has unknown impact and remote attack vectors, aka DB21.

The Core RDBMS component in Oracle Database 9.0.1.5+, 9.2.0.8, 9.2.0.8DV, 10.1.0.5, and 10.2.0.3 allows remote attackers to cause a denial of service (CPU consumption) via a crafted type 6 Data packet, aka DB20.

Multiple unspecified vulnerabilities in Oracle Database 10.2.0.3 allow remote authenticated users to have an unknown impact via (1) EXFSYS.DBMSRLMGRUTL in Rules Manager (DB11) and (2) Program Interface (DB13).
