Hi,
I've found a bug on wap/wtls_pdu.c file, wtls_payload_dump function.
This function may be called with an NULL payload (when wtls_decrypt
outputs the error: ERROR: wtls_decrypt: Rejected packet due to bad MAC)
which causes a segmentation fault.
I've attached the patch with the fix for the current trunk version.
Best regards,
Armindo Antunes
