mgetty can be configured to run an external program to decide whether or not to answer an incoming call based on Caller ID information. Versions of mgetty prior to 1.1.29 would overflow an internal buffer if the caller name reported by the modem was too long. Additionally, the faxspool script supplied with versions of mgetty prior to 1.1.29 used a simple permissions scheme to allow or deny fax transmission privileges. This scheme was easily circumvented because the spooling directory used for outgoing faxes was world-writable.
