on one of my computers, pam_acess.so segfults, ok, to be precise: sshd segfaults, since i included pam_access.sp in my config.
I guess the bug is in the code, that looksup the groups the user is in. A full description of the Bug is here:
http://bugs.gentoo.org/show_bug.cgi?id=65567


Please tell me which data or info you need.
I will provide as much help as i can.

No reactions? What's wrong? Did i do anything wrong? Is this "bug" to harmless? Is pam_access deprecated?

I'm not sure if this is your problem, but one thing that can cause this is if a PAM module does not correctly handle the appdata_ptr.


If the module doesn't pass it back (eg passes a null) then sshd ( <= 3.8.1p1, I think) will segfault when it attempts to deref it. From 3.9p1, sshd will check for null and give a warning instead of crashing.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
