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-writable, this scheme was easily circumvented.

Update :

The installation of mgetty-sendfax on Mandrake Linux 8.2 relied on
macros that are non-existent, which would result in fresh installs of
mgetty-sendfax being unable to work. Updated packages for 8.2 correct
this."

Mgetty is a getty replacement for use with data and fax modems.

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.

All users of Mgetty should upgrade to these errata packages, which
contain Mgetty 1.1.30 and are not vulnerable to these issues."
