multiple vulnerabilities :

  - MODIFIED SQL DATA table function is not dropped even if 
    the maintainer does not have privileges to maintain the 
    objects. (IZ46773)

  - It may be possible for an unauthorized user to insert,
    update, or delete rows in a table. (IZ50078)
 
  - An user without 'SETSESSIONUSER' privilege can perform
    'SET SESSION AUTHORIZATION'. (IZ55883)

  - The 'DASAUTO' command can be run by a non-privileged
    user. (IZ40340)");
