Error description
UNSTRING statement reads past the end of sending field causing false matches with DELIMITER value. UNSTRING may put one extra byte into the DELIMITER field.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL V5 and later * * releases who are using UNSTRING statement. * **************************************************************** * PROBLEM DESCRIPTION: The COBOL runtime UNSTRING routine * * does one extra delimiter check beyond * * the end of the sending field, causing * * incorrect UNSTRING result. * **************************************************************** * RECOMMENDATION: Apply the provided PTF * **************************************************************** During UNSTRING processing, the COBOL runtime fails to check for the remaining length of the sending field, and uses dirty byte values following the end of the field to do one extra delimiter comparison before stopping. This could lead to erroneous UNSTRING result.
Problem conclusion
The COBOL Runtime is corrected to stop properly at the end of the sending field when the remaining field length is too short to do delimiter comparison.
