[asterisk-bugs] [JIRA] (ASTERISK-25439) Segfault in find_entry () from /usr/lib/libpj.so.2 (dns_resolver, qualify_contact)

George Joseph updated ASTERISK-25439:
-------------------------------------

    Assignee: Dmitriy Serov  (was: George Joseph)
      Status: Waiting for Feedback  (was: Open)

Possible cause...
pjproject defines a maximum hostname size of 128 (which is way too short in my opinion).  If it's passed a hostname longer than that that, it segfaults.

Can you try compiling pjproject with PJ_MAX_HOSTNAME set to something very large and see if the issue still happens?

I'm going to put a check in Asterisk anyway to prevent us from sending the hostname if it's too long.
