Build Information:
Unfortunately, I can't. That menu item doesn't do anything. v1.11.2 as
downloaded.
--
The code for dealing with PKT_CCC_KRB_REALM (6) is attempting to validate the
contents of the sub-option too stringently. The content of the realm name is
an RFC 1035-encoded FQDN. So if one specified BASIC.1, you'd get the content
of 05 42 41 53 49 43 01 31 00. However, the test is looking for A-X, ., /, \,
=, ", ,, and :. But the 01 byte in there will cause the test to fail, and then
Wireshark will claim that the content of that option is ill-formed.
