The Zoo kernel contains at least three if statements that check if the protocol of a URL is http (or ftp). These statements must be modified if Zoo is to handle requests over the https protocol. Attached are modified versions of zoo_service_internal.c (modified in lines 1214 and 1976) and zoo_service_loader.c (modified from line 1182). These changes pertain to revision # 452 in the source code repository.

In the following code fragment occurring twice in zoo_service_loader.c, GetProcAddress or dlsym will return NULL if a user has mistyped the service name (the WPS Identifier parameter):

#ifdef WIN32
	typedef int (CALLBACK* execute_t)(char***,char***,char***);
	execute_t execute=(execute_t)GetProcAddress(so,fname);
#else
	typedef int (*execute_t)(char***,char***,char***);
	execute_t execute=(execute_t)dlsym(so,fname);
#endif

This will cause a crash when attempting to invoke the function at the address given by execute:

*eres=execute(&m,&request_input_real_format,&request_output_real_format);

There should be a check to avoid this happening (with an error message).

• I'm in the process of creating a nabble.com forum for zoo-discuss
• new messages are now being archived there
• however for old messages apparently I must send the nabble admins our .mbox archive (in that specific format only)
• I am not sure where Mailman is running (which machine) and if Mailman stores messages in .mbox format by default, so I need some advice or assistance
