 It seems minicom(distributed with slak3.4) have some overflow

 If this is new, I may post an exploit if prompted to.

What kind of exploit will you be able to get?  Minicom is setgid uucp on
my system, the worst you can do is upset UUCP operations, which don't happen
here anyway, or possibly change the permissions on the dev file.  System
is Slack 3.2.


 True enough, minicom is only sgid uucp in latest RedHat & Slakware
releases, though keep in mind if you rebuild minicom from source it will
install it setuid root by default.
