descriptionA bug was fixed in pam_ldap 162 with the pam_filter mechanism which is commonly used for host-based access restriction in environments using LDAP for authentication. Mandrake Linux 9.1 provided pam_ldap 161 which had this problem and as a result, systems relying on pam_filter for host-based access restriction would allow any user, regardless of the host attribute associated with their account, to log into the system. All users who use LDAP-based authentication are encouraged to upgrade immediately.
