Anyone running a version of sliplogin older than sliplogin-2.1.0
(which can be gotten from sunsite.unc.edu:/pub/Linux/system/Network/serial
or ftp.uk.linux.org:/pub/linux/Networking/transports) should remove it
or upgrade it immediately.
It does
setuid(0);
if (s = system(logincmd)) {
:
}
without clearing the environment first. Therefore, anybody can get
root trivially.
The sliplogin from NetKit-B-0.06 is affected.
Current RedHat sliplogin is not affected.
Others I don't know about.
