Credits:

Details:
Oracle Database Vault provides additional protections from malicious privileged 
users.  The protections include separation of duty for some tasks like user 
account management.  Any user with SYSDBA privilege (CVE-2011-2322) or 
DV_ACCTMGR role (CVE-2011-3511) can bypass these protections and change any 
user's password (including Oracle Database Vault Owner user password) calling 
the OCIPasswordChange client API (the 'password' command in SqlPLUS uses this 
API).

Impact:
Users granted SYSDBA privilege (CVE-2011-2322) or DV_ACCTMGR role 
(CVE-2011-3511) can change any user's password (including the Oracle Database 
Vault Owner user password) calling the OCIPasswordChange client API ('password' 
command in SqlPLUS).
