| Revoking all default installation privilege assignments from PUBLIC is not required at this time. However, execute permissions to the specified packages is required to be revoked from PUBLIC. Removal of these privileges from PUBLIC may result in invalid packages in version 10.1 and later of Oracle and an inability to execute default Oracle applications and utilities. To correct this problem, grant execute privileges on these packages directly to the SYSMAN, WKSYS, MDSYS and SYSTEM accounts as well as any other default Oracle database and custom application object owner accounts as necessary to support execution of applications/utilities installed with an Oracle Database Server. At a minimum, revoke the following: From SQL*Plus: revoke execute on UTL_FILE from PUBLIC; revoke execute on UTL_SMTP from PUBLIC; revoke execute on UTL_TCP from PUBLIC; revoke execute on UTL_HTTP from PUBLIC; revoke execute on DBMS_RANDOM from PUBLIC; revoke execute on DBMS_LOB from PUBLIC; revoke execute on DBMS_SQL from PUBLIC; revoke execute on DBMS_SYS_SQL from PUBLIC; revoke execute on DBMS_JOB from PUBLIC; revoke execute on DBMS_BACKUP_RESTORE from PUBLIC; revoke execute on DBMS_OBFUSCATION_TOOLKIT from PUBLIC; |
