Two vulnerabilities were discovered in mgetty versions prior to 1.1.29. An internal buffer could be overflowed if the caller name reported by the modem, via Caller ID information, was too long. As well, the faxspool script that comes with mgetty used a simple permissions scheme to allow or deny fax transmission privileges. Because the spooling directory used for outgoing faxes was world-writeable, this scheme was easily circumvented.
