"According to its version, the IBM DB2 server running on the remote
host is affected by one or more of the following issues :

  - There is an unspecified security vulnerability
    related to a 'DB2FMP' process. (IZ20352)

  - On Windows, the 'DB2FMP' process is running with OS
    privileges. (JR30026)

  - The CLR stored procedure deployment feature of IBM 
    Database Add-Ins for Visual Studio can be used to
    escalate privileges or launch a denial of service
    attack against a DB2 server. (JR28432)

  - The password used to connect to the database can be
    seen in plaintext in a memory dump. (JR27422)

  - There is a possible stack variable overrun in
    'SQLRLAKA()'. (IZ16346)

  - A local privilege escalation vulnerability via file
    creation can result in root-level access. (IZ12735)

  - There are possible buffer overflows involving 'XQUERY', 
    'XMLQUERY', 'XMLEXISTS', and 'XMLTABLE'. (IZ18434)

  - A specially crafted client CONNECT request could
    crash the server. (IZ07299)

  - There is an unspecified remote buffer overflow in
    DAS server code. (IZ22188)

  - INSTALL_JAR can be used to create or overwrite
    critical system files. (IZ21983)");
