I already fixed this NULL pointer dereference in ctutil.c revision 1.12 on
23 Sep 2002.  It isn't necessary to pass a NULL context as you suggest,
since we just computed an appropriate context (ctx).

Cheers,

The following code dereferences a NULL pointer in ctutil.c

        if (!con) {
                ctx = (CS_CONTEXT *) ctx_tds->parent;
                if (ctx->_servermsg_cb) 
                        ret = ctx->_servermsg_cb(con->ctx,con,&errmsg);
                                                 ^^^^^^^^

attached is a simple patch to call servermsg_cb with a null context in this
case
