IJ09629: HUB TEMS CRASH WHEN TACMD EXECUTECOMMAND WITH -C "" EMPTYSTRING SPECIFIED.

IBM Tivoli Monitoring 6.3.0 Fix Pack 7 Service Pack 1 (6.3.0.7-TIV-ITM-SP0001)

APAR status

• Closed as program error.

Error description

• TS001121758
  APAR IV78192 added auditing for tacmd
  GetFile/PutFile/ExecuteCommand.
  
  The problem is, if the user specifies a command string
  consisting of the empty string, the Hub crashes:
  
  - the CLI does not send the empty command request to the Hub.
  
  - however, it does still send a request to the Hub to audit the
  command.
  
  - the parameters it sends should include the command that was
  run.
  
  - the Hub doesn't tolerate missing parameters and ends up with a
  null pointer which it then attempts to use.
  

Local fix

• Do not send tacmd executeCommand parameters with a null string
  argument.
  

Problem summary

• Since ITMv630 FP7, an audit record is generated after a GetFile,
   PutFile or ExecuteCommand request runs.  The code was not
  accommodating missing parameters and was using a system call
  that was not thread-safe the consequence of which was a possible
   access violation.
  
  
  The Hub may crash when a tacmd request runs to perform a
  GetFile, PutFile or ExecuteCommand request.
  

Problem conclusion

• The code was amended to tolerate missing parameters and to
  guarantee that it is thread-safe.
  
  
  The fix for this APAR is contained in the following maintenance
  packages:
