[PATCH]: Fix potential security hole in Cygwin version
...n check_nt_auth() is called in auth1.c and auth2.c with implicitly dereferencing the pointer to struct passwd to get the pw_uid member as parameter. This struct passwd pointer can be NULL if the user isn't found in /etc/passwd. Other similar funcs as auth_pam_password() are called getting the structy passwd pointer itself as parameter, testing it for NULL inside of the function. Changing the check_nt_auth() to behave that way and changing auth1.c and auth2.c accordingly solves that problem. Patch follows. Thanks, Corinna Index: auth1.c =======================================================...
