APAR status

  • Closed as program error.

Error description

  • Error Message: "integrity check failed" will happen while
unwrapping token in JGSS if the token buffer contains extra data
apart from the actual token data. JGSS will treat the whole
token buffer as the token to be unwrapped which is incorrect if
the token buffer length is larger than the actual token data
length or offset is not zero.
.
Stack Trace: N/A
.

  • 



Problem summary


    

  • JGSS wrap token buffer is wrongly handled.

    



Problem conclusion


    

  • The fix now takes the offset and input length into consideration
when retrieving the actual token from the token buffer.
