"According to its version, the installation of IBM DB2 9.5 running on
the remote host is prior to Fix Pack 9. It is, therefore, affected by
the following vulnerabilities :

  - Incorrect, world-writable file permissions are in place
    for the file 'NODES.REG'. (IC79518)

  - An unspecified error can allow attacks to cause a
    denial of service via unspecified vectors. (IC76899)

  - A local user can exploit a vulnerability in the bundled
    IBM Tivoli Monitoring Agent (ITMA) to escalate their
    privileges. (IC79970)

  - An unspecified error in the DB2 Administration Server
    (DAS) can allow remote privilege escalation or denial
    of service via unspecified vectors. Note that this
    issue does not affect Windows hosts. (IC80728)

  - An authorized user with 'CONNECT' privileges from
    'PUBLIC' can cause a denial of service via unspecified
    methods related to DB2's XML feature. (IC81379)

  - An authorized user with 'CONNECT' and 'CREATEIN'
    privileges on a database can perform unauthorized
    reads on tables. (IC81387)");
