"According to its version, the installation of IBM DB2 8 running on the
remote host is affected by multiple issues :

  - By sending malicious DB2 UDB v7 client CONNECT/DETACH
    requests it may be possible to crash the remote DB2 
    server. (IZ08134)

  - Failure to switch the owner of the 'DB2FMP' process
    may lead to a security vulnerability on Unix / Linux
    platforms. (IZ20350)

  - DAS server code is affected by a buffer overflow 
    vulnerability. (IZ22004)

  - Using INSTALL_JAR, it may be possible to create and 
    overwrite critical files on the system. (IZ22142)

  - DB2 does not mark inoperative or drop views and triggers
    if the definer cannot maintain the objects. (IZ22287)

  - By sending malicious packets to 'DB2JDS', it may be 
    possible to crash the remote DB2 server. (JR29274)

  - While running on Windows 'DB2FMP' runs with OS
    privileges. (JR30228)");
