PK08010: DFHWB0001 AN ABEND (CODE 0C4/AKEA) HAS OCCURRED AT OFFSET X'5764' IN MODULE DFHWBSR

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When using the CICS Web security analyser, DFH$WBSA, a scan of
  the input data may incorrectly scan beyond the end of the data
  resulting in an abend0c4 at offset X'5764' in module DFHWBSR.
  An alternative symptom may be a long delay or loop as DFHWBSR
  scans through large amounts of data searching for an ascii space
  character.

  ****************************************************************
  When using the security analyser (DFH$WBSA) for the CICS Web
  Server, an abend 0C4 can occur because a search is performed for
  'DFHWBSN' or a space in the input data. The search is
  incorrectly done in ASCII whereas the data has already been
  converted to EBCDIC. Another symptom is a long response time
  accompanied with a loop within CICS whilst storage is searched
  for an ASCII space.
  Additional keywords: S0C4 abend0c4 DFHWBSN
  

Problem conclusion

• DFHWBSR has been changed in routine wbrq_receive_http_request to
  search for 'DFHWBSN' and space in EBCDIC rather than ASCII.
