Linux Distributions are Vulnerable to the /bin/login Overflow
It seems that while Redhat Linux and Caldera Linux distributions are
immune to the recent /bin/login environment overflow, other Linux
distributions are not. Several Linux distributions install /bin/login with
SysV login options enabled.
A quick way to check for SysV option capabilities is to type "login", then
enter "root testenv1=test" at the login: prompt. Supply your root passwd,
and look for "testenv1" in the output of set. If it is set, then your copy
of /bin/login supports SysV options, and is probably vulnerable.
