Vulnerability Development: Re: BUG in ftp client on *BSD and Solaris system?

[T0aD <toad () skreel org>]

Hello 

Apparently this aint no 'security bug' in here.
The shell prints out this string to notice user he's
quitting job or process while sending a signal with Ctrl + 4 ('^\'),
a signal also known as SIGQUIT (signal 3)

from man signal:
    SIGQUIT         create core image       quit program

Oh well yeah under linux it doesnt seem to print anything except while playin'
around (talking about bash, the default shell):

(nofuture)$ read &
[1] 1678
(nofuture)$ kill -QUIT 1678

[1]+  Stopped                 read
(nofuture)$ fg
read
Quit                           <-- i let you guess if it means its 'vulnerable'..
(nofuture)$ 

-- toad wastin' time

Still unpatched:
- some brains
