"According to its version, the installation of IBM DB2 9.7 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. (IC63548)

  - A privilege escalation vulnerability exists in the
    DB2STST program (on Linux and Unix platforms only). 
    (IC65742)

  - A malicious user could use the DB2DART program to 
    overwrite files owned by the instance owner. (IC65762)

  - The scalar function REPEAT contains a buffer overflow
    that a malicious user with a valid database connection 
    could manipulate, causing the DB2 server to trap. 
    (IC65935)

  - Special group and user enumeration operation on the DB2 
    server or DB2 Administrator Server (DAS) could trap 
    when running on Windows 2008. (IC66643)

  - It is possible to execute non-DDL statements even after
    an user's DBADM authority has been revoked. (IC66815)

  - If the database configuration parameter 'AUTO_REVAL' is
    set to 'IMMEDIATE', system granted privileges are not
    regenerated. (IC67008)

  - 'Monitor Administrative Views' available in SYSIBMADM
    schema are publicly viewable. (IC67819)

  - 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. (IC68055)

  - By sending a specially crafted packet to the Tivoli 
    Monitoring Agent (KUDDB2), which listens on TCP port 
    6014 by default, it may be possible to trigger a denial 
    of service condition. (IC68762)");
