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

1) An unspecified error related to DAS can be exploited write to arbitrary files and gain root privileges.

2) An unspecified error in the DB2JDS service can be exploited to cause a crash via specially crafted packets.

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

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

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

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