Some vulnerabilities have been reported in IBM DB2, where one has an unknown impact and others can be exploited by malicious users to potentially perform certain actions with escalated privileges, cause a DoS (Denial of Service), to bypass certain security restrictions, or potentially compromise a vulnerable system.

1) An unspecified error can be exploited to insert, update, or delete rows in a table without having required privileges.

2) An unspecified error exists related to a table function when the definer loses required privileges.

These vulnerabilities are reported in DB2 9.1 prior to FP8, DB2 9.5 prior to FP4, and DB2 9.7 prior to FP2.

3) An unspecified error in the handling of "SET SESSION AUTHORIZATION" statements can be exploited to execute this statement without having the required privileges.

This vulnerability is reported in DB2 9.1 prior to FP8.

4) The "DASAUTO" command can be run by non-privileged users.

This security issue is reported in DB2 9.1 prior to FP8 and DB2 9.5 prior to FP4.

5) An error in the implementation of certain DB2 table functions can potentially be exploited to compromise a vulnerable system.
