"According to its version, the installation of IBM DB2 9.1 running on
the remote host is affected by one or more of the following issues :

  - The 'MODIFIED SQL DATA' table function is not dropped
    when a definer loses required privileges to maintain
    the objects. (IZ46773)

  - A privilege escalation vulnerability exists in the
    DB2STST program (on Linux and Unix platforms only). 
    (IC65408)

  - A malicious user could use the DB2DART program to 
    overwrite files owned by the instance owner. (IC65749)

  - A heap overflow vulnerability exists in the 'REPEAT' 
    scalar function. A remote attacker with a valid 
    database connection could exploit this issue to execute
    arbitrary code subject to the privileges under which
    the database service operates. (IC65922)

  - Special group and user enumeration operation on the DB2 
    server or DB2 Administrator Server (DAS) could trap 
    when running on Windows 2008. (IC66099)

  - A weakness in the SSL v3 / TLS protocol involving
    session renegotiation may allow an attacker to inject 
    an arbitrary amount of plaintext into the beginning of
    the application protocol stream, which could facilitate
    man-in-the-middle attacks. (IC67848)");
