IBM DB2 unauthorized table access

db2-cve20134033-priv-esc (86093) The risk level is classified as MediumMedium Risk

Description:

A vulnerability in IBM DB2 could allow an authenticated remote attacker to temporarily gain SELECT, INSERT, UPDATE or DELETE privileges on a table. To exploit the vulnerability, the attacker 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.
