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

  - The 'db2dart' tool executes the 'tput' command which
    effectively allows a malicious user to run commands 
    as the DB2 instance owner (IZ03646).

  - 'db2watch' and 'db2freeze' have some unspecified
    vulnerability (IZ03655).

  - Incorrect permissions on ACLs for 'DB2NODES.CFG'
    (JR26989).

  - A local user may be able to gain root privileges using
    an unspecified vulnerability in several set-uid
    binaries (IZ07018).

  - A buffer overflow and invalid memory access 
    vulnerability exists in the DAS server code (unknown).");
