Fedora 29: mgetty Security Advisory - Command Injection And Buffer Overflow

The mgetty package contains a "smart" getty which allows logins over a

serial line (i.e., through a modem). If you're using a Class 2 or 2.0

modem, mgetty can receive faxes. If you also need to send faxes,

you'll need to install the sendfax program.

If you'll be dialing in to your system using a modem, you should

install the mgetty package. If you'd like to send faxes using mgetty

and your modem, you'll need to install the mgetty-sendfax program. If

you need a viewer for faxes, you'll also need to install the

mgetty-viewfax package.
