"The installation of IBM DB2 9.5 running on the remote host does not
have any Fix Packs applied. It is, therefore, affected by one or more
of the following issues :

  - There is a security vulnerability in the 'NNSTAT'
    procedure on Windows platforms only that allows low-
    privileged users to overwrite arbitrary files.
    (IZ10776)

  - There is a security vulnerability in the
    'SYSPROC.ADMIN_SP_C' procedure on Windows platforms 
    that allows users to load arbitrary library and 
    execute arbitrary code in the system. (IZ10917)

  - An unspecified vulnerability affects 'DB2WATCH' and
    'DB2FREEZE' on Solaris platforms. (IZ12994)

  - An authenticated, remote user can cause the DB2 instance
    to crash by passing specially crafted parameters to 
    the 'RECOVERJAR' and 'REMOVE_JAR' procedures. (IZ15496)

  - There is an internal buffer overflow vulnerability in
    the DAS process that could allow arbitrary code 
    execution on the affected host. (IZ12406)

  - A local attacker can create arbitrary files as root 
    on Unix and Linux platforms using symlinks to the 
    'dasRecoveryIndex', 'dasRecoveryIndex.tmp', 
    '.dasRecoveryIndex.lock', and 'dasRecoveryIndex.cor' 
    files during initialization. (IZ12798)

  - There are possible buffer overflows involving 'XQUERY', 
    'XMLQUERY', 'XMLEXISTS', and 'XMLTABLE'. (IZ18431)

  - There is a security vulnerability related to a 
    failure to switch the owner of the 'db2fmp' process
    affecting Unix and Linux platforms. (IZ19155)

  - When a memory dump occurs, the password used to connect
    to the database remains visible in plaintext in the 
    memory dump file. (JR28314)

  - 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. (JR28431)

  - A flaw exists in the db2ls command that allows a local
    attacker to write to any file on the system through the
    use of symbolic links. Note that this issue does not
    affect Windows systems. (IZ14939)");
