"The installation of IBM DB2 9.5 running on the remote host does not
have Fix Pack 2 applied. It is, therefore, affected by the following
issues :

  - DB2 does not mark inoperative or drop views and triggers
    if the definer cannot maintain the objects (IZ22307).

  - Password-related connection string keyword values may
    appear in trace output (IZ28489).

  - There is an unspecified vulnerability in the way CLR 
    Stored Procedures for Visual Studio from IBM database 
    add-ins are deployed (JR28431). 

  - There is an unspecified buffer overflow in DAS server
    code (IZ22190).

  - INSTALL_JAR can be used to create or overwrite critical
    files on a system (IZ22143).

  - On Windows, the db2fmp process is running with OS
    privileges (JR30227).");
