"According to its version, the installation of IBM DB2 9.8 running on
the remote host is prior to Fix Pack 5. It is, therefore, affected by
multiple vulnerabilities :

  - An authorized user with 'CONNECT' privileges from
    'PUBLIC' can cause a denial of service via unspecified
    methods related to DB2's XML feature. (CVE-2012-0712)

  - An unspecified information disclosure vulnerability
    exists related to the XML feature that can allow
    improper access to arbitrary XML files. (CVE-2012-0713)

  - An error exists related to the Distributed Relational
    Database Architecture (DRDA) that can allow denial of
    service conditions when processing certain request.
    (CVE-2012-2180)

  - A security bypass vulnerability exists due to the
    persistence of privileges when they're removed from
    users. An attacker can exploit this to execute non-DDL
    statements even if their privileges have been revoked.

  - An unspecified flaw exists that allows an attacker to
    cause a denial of service condition when Self Tuning
    Memory Manager (STMM) is enabled and DATABASE_MEMORY is
    set to AUTOMATIC.");
