The security hole that this program has is that it has to open
/dev/tty's files in order to talk to the serial ports. It has a
bug that leaves the permissions wrong when it is done. So in order
to exploit this hole then one has to have access to a shell(Logged in).
Minicom is a program that lets you talk to a serial port/modem. It
is similar in function to cu or tip but it has a better terminal
emulation environment. I suspect most of you will not use this in
todays world of tcp/ip .
I suspect that it is installed but not used. The default fermi install
does install it.
To see if you have it do rpm -q minicom
The command should come back with a version if it is installed.
To remove rpm -e minicom
If one were to disable it then anyone who wanted to use it would
not be able to. It is normally started by a person running it
via a shell.
