Hi,

I'm a PhD student. I analyzed the Wireshark source code and found that
gcry_md_open missing error handling code in serval places.

I think it's unsafe to assume the library function would be correct. It would
be better if we could handle the error properly.

Attached please find the patch against wireshark-2.5.1-428-gd95d6a59
(2018-03-02 23:25). Hopefully, it can solve these potential bugs.

Best,
Zhouyang
