DB2 FOR LUW / DB2FORLUW / A10 - DB2

DB2 server contain a security vulnerability which could allow an 
authenticated user to temporarily gain SELECT, INSERT, UPDATE or 
DELETE privileges on a table. To exploit the vulnerability, the 
user would need to have a valid security credential to connect 
to the database and EXPLAIN, SQLADM or DBADM authority. 
 
Under unspecified conditions, a user with the above authorities 
will be able to execute a DML statement such as SELECT, INSERT, 
UPDATE and DELETE on a table that they do not have authority 
for. Only DML statements are vulnerable. 
 
The following query will show which user has EXPLAIN / SQLADM / 
DBADM authority but no DATAACCESS authority: 
 
select substr(grantor,1,10) grantor , substr(grantee,1,20) 
grantee , granteetype, explainauth, dbadmauth, sqladmauth, 
dataaccessauth from SYSCAT.DBAUTH where dataaccessauth = 'N' and 
(explainauth = 'Y' or dbadmauth = 'Y' or sqladmauth = 'Y')
