Summary
Security vulnerabilities have been discovered in IBM DB2 shipped with
IBM PureData System for Transactions.
Vulnerability Details
CVE ID: CVE-2014-6209
DESCRIPTION:
IBM DB2 contains a denial of service vulnerability. A remote, authenticated
DB2 user could exploit this vulnerability by executing a specially-crafted
ALTER TABLE statement on an identity column . This may cause DB2 server
to terminate abnormally. To exploit the vulnerability, the malicious
user needs to have valid security credentials to connect to DB2 and the
authorization associated with the authorization ID of the connection would
need to match one of the authorization scenarios listed below. Note that
these authorities or privileges could be obtained by membership in a group
or by assignment of certain role.
1) CONTROL or ALTER privilege on a table
The user would need either CONTROL or ALTER privilege on a table to execute
the ALTER TABLE statement. Customer could consult the SYSCAT.TABAUTH table to
determine the users, roles, and groups that have CONTROL privilege or ALTER
privilege on a table. Furthermore, the owner of a table has implicit control
privilege and the DBADM authority has implicit control privilege on all
tables. Customer could look up owner of a table from the SYSCAT.TABLES table.
2) ALTERIN privilege on any schema that contains a table
User with this privilege could execute ALTER TABLE statement on any table
in the schema. Customer could consult the SYSCAT.SCHEMAAUTH table to check
for users, roles, and groups with this privilege. Also, customer could
check the SYSCAT.TABLES for existence of tables in the schema.
3) CREATETAB authority on a database and USAGE privilege on at least one
table space
With this authority, the user could create a table and then execute ALTER
TABLE statement on that table. Customer could lookup the SYSCAT.DBAUTH
table to find out users, roles, and groups with CREATETAB authority and
check the SYSCAT.TBSPACEAUTH table for users, roles, and groups with USAGE
privileges on table spaces.

CVE ID: CVE-2014-6210
DESCRIPTION:
IBM DB2 contains a denial of service vulnerability. A remote, authenticated
DB2 user could exploit this vulnerability by issuing multiple ALTER TABLE
statements on the same column. This may cause DB2 server to terminate
abnormally. To exploit the vulnerability, the malicious user needs to
have valid security credentials to connect to DB2 and the authorization
associated with the authorization ID of the connection would need to
match one of the authorization scenarios listed below. Note that these
authorities or privileges could be obtained by membership in a group or
by assignment of certain role.
1) CONTROL or ALTER privilege on a table
The user would need either CONTROL or ALTER privilege on a table to execute
the ALTER TABLE statement. Customer could consult the SYSCAT.TABAUTH table to
determine the users, roles, and groups that have CONTROL privilege or ALTER
privilege on a table. Furthermore, the owner of a table has implicit control
privilege and the DBADM authority has implicit control privilege on all
tables. Customer could look up owner of a table from the SYSCAT.TABLES table.
2) ALTERIN privilege on any schema that contains a table
User with this privilege could execute ALTER TABLE statement on any table
in the schema. Customer could consult the SYSCAT.SCHEMAAUTH table to check
for users, roles, and groups with this privilege. Also, customer could
check the SYSCAT.TABLES for existence of tables in the schema.
3) CREATETAB authority on a database and USAGE privilege on at least one
table space
With this authority, the user could create a table and then execute ALTER
TABLE statement on that table. Customer could lookup the SYSCAT.DBAUTH
table to find out users, roles, and groups with CREATETAB authority and
check the SYSCAT.TBSPACEAUTH table for users, roles, and groups with USAGE
privileges on table spaces.
