remote host is affected by one or more of the following issues :

  - A local user may be able to gain root privileges using

  - The 'b2dart' tool executes a TPUT command, which
    effectively allows users to run commands as the DB2
    instance owner. (IZ03647)

  - A buffer overflow and invalid memory access 
    vulnerability exist in the DAS server code. (IZ05496)

  - An unspecified vulnerability in 'SYSPROC.ADMIN_SP_C'.
    (IZ06972)

  - An unspecified vulnerability exists due to incorrect
    authorization checking in 'ALTER TABLE' statements.
