Affected Version:

What steps will reproduce the problem?
1. Load the attached file
2. Look at the GTP RAND value in the second or third Quintuplet.

What is the expected output? What do you see instead?
The RAND value in the packet details is different from that in the packet bytes.

Please provide any additional information below.
The bug is in the packet-gtp.c, decode_quintuplet() function, in the line:
  proto_tree_add_text(ext_tree_quint, tvb, offset + q_offset, 16, "RAND: %s", tvb_bytes_to_str(tvb, offset, 16));

The correct code would be:
  proto_tree_add_text(ext_tree_quint, tvb, offset + q_offset, 16, "RAND: %s", tvb_bytes_to_str(tvb, offset + q_offset, 16));

Wrong issue tracker. This issue tracker is about the Gerrit Code Review Project, but what you describe seems to have nothing to do with Gerrit.
