CVE ID: CVE-2013-4033
The IBM DB2 products listed below 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 DATAACCESS authority for. Only DML statements are vulnerable.
