IC87885: USING A COLUMN WITH EXPLICIT INLINE LENGTH MAY CAUSE BUFFER OVERRUN

DB2 Version 10.1 Fix Pack 2 for Linux, UNIX, and Windows

APAR status

• Closed as program error.

Error description

• DB2 supports specification of an inline length for a column of
  type XML/LOB/user defined type.
  Under the scenario where this column is used as an input to a
  function, DB2 might ignore the
  inline length specification and use the default length for the
  datatype.
  
  This can lead to buffer overruns and memory corruption if the
  data length exceeds the default datatype length.
