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

  - A local user may be able to overwrite arbitrary files,
    create arbitrary world-writeable directories, or gain
    root  privileges via symlink attacks or specially
    crafted  environment variables. (IY98210 / IY99261)

  - A user may be able to continue to execute a method even 
    once privileges for the method have been revoked.
    (IY88226,  version 8 only)

  - There is an unspecified issue allowing for privilege
    elevation when DB2 'execs' executables while running as 
    root. (IY98206 / IY98176)

  - There is an unspecified vulnerability related to
    incorrect authorization routines. (JR25940, version 8
    only)

  - There is an unspecified vulnerability in 
    'AUTH_LIST_GROUPS_FOR_AUTHID'. (IZ01828, version 9.1 
    only)

  - There is an unspecified vulnerability in the 'db2licm'
    and 'db2pd' tools. (IY97922 / IY97936)

  - There is an unspecified vulnerability involving
    'db2licd' and the 'OSSEMEMDBG' and 'TRC_LOG_FILE'
    environment variables. (IY98011 / IY98101)

  - There is a buffer overflow involving the 'DASPROF'
    environment variable. (IY97346 / IY99311)

  - There is an unspecified vulnerability that can arise 
    during instance and FMP startup. (IZ01923 / IZ02067)

  - The DB2JDS service may allow for arbitrary code
    execution without the need for authentication due to a
    stack overflow in an internal sprintf() call.
    (IY97750, version 8 only)

  - The DB2JDS service is affected by two denial of service
    issues that can be triggered by packets with an invalid
    LANG parameter or a long packet, which cause the process
    to terminate (version 8 only).

Note that there is currently insufficient information to determine to
what extent the first set of issues overlaps the others." );
