(Background: My SELinux hosts are all F15, fairly base installation, with the unconfined module disabled) I have a host that is for random hackery, and hence is (or at least is allowed to be) less secure than the others. I have a user who made a CGI (running under apache; python, in case that matters) that pulls things from elsewhere on the web and then sends email with the results. This generates a pretty large number of AVC denials, which I suppose is reasonable since that behaviour looks an awful lot like "I just got hijacked and am now being used for spam distribution". One thing I was genuinely surprised by though is that the mail-related denials all came in for httpd_user_script_t , rather than sendmail_t or something, and that no attempt to transition to sendmail_t seems to have occured or been denied or anything, as I'd have expected (it sends mail with /bin/mail ). FWIW, here's the AVCs: http://fpaste.org/ZyHg/ (uses date from the input form only) http://fpaste.org/M9Fq/ (goes out and talks to another website) I've learned a lot about SELinux recently, but it's all been piecemeal, so this is more of a "what's the right thing?" question designed to for me to learn from more than "what's the fastest way to fix this?". So, what's the right way to handle this situation? httpd_user_script_exec_t doesn't do the trick at all (which is probably good since it turns out user_u can set that with chcon, which I didn't expect). Is there some way without installing a module (i.e. with semanage or similar) to indicate to SELinux "Yeah, this script over here? It can talk to the web" (or "send email")? Is there a way to indicate that system-wide without installing a module? (not that I would, just curious) If doing it via module, it's best to create a bobs_script_exec_t and bobs_script_t and do everything for those types, rather than httpd_user_script_exec_t and friends, right? This means that a user making a non-trivial CGI has to come talk to me, which is a tad unfortunate but not horrible. Thanks for all enlightenment here, and please feel free to go the "you're thinking about it wrong" route; I'm really wanting to learn. -Robin -- http://singinst.org/ : Our last, best hope for a fantastic future.
