Hi,
I am new to PAM. I was just trying out with some test code using PAM
interfaces. This is something that I noticed in pam_start.
If NULL is passed for either the service name or pam handle in the
pam_start interface, it results in segmentation fault. When I went
through the code I found that memory is allocated for pam handle without
checking if it is NULL.
if ((*pamh = calloc(1, sizeof(**pamh))) == NULL)
But the parameters for user and service name are checked before
allocating memory. But I am not sure why it results in a segmentaion
fault when the service name is NULL.
Am I missing something ? Please help
Regards
Rohit
