Subj: WARNING on PKZIP/UNZIP!!!!!!

------------------------------------------------
|
||
This message was sent thru the SDS Coordinator's Echo, with a pretty stern
|
||
warning on the use of Zip.
|
||
|
||
The SDS has been asked by several of its members to BAN the use of Zipped
|
||
Files because of the ability to embed practically anything in its comments
|
||
field, which are shown anytime anything is done with the packet.
|
||
|
||
I debabted whether or not to relate this here, as the information is
|
||
particularly sensitive to SYSOP's and if this gets out to people - the full
|
||
scale assaults might begin.
|
||
|
||
Suffice it to say, it can be used in any setting, uploads or even net-mail.

||

What follows, is an article I received for MetroLink, the Net 107 newsletter.
|
||
Just thought it may be of interest to you all!

ALERT! ALERT! ALERT!
|
||
|
||
As most of you know it is possible to reprogram your
|
||
keyboard (and other things) using ANSI Escape sequences. What may
|
||
not be so readily apparent, however, is that Phil Katz' ZIP
|
||
programs will allow the use of ANSI in the comments section. This
|
||
means that everytime you do anything to that ZIP file which
|
||
causes the comment to be displayed you run the risk of having
|
||
your keyboard redefined. I have received several such "innocent
|
||
looking" files in the last two weeks. One caused my F1 key to
|
||
display a wide DOS Directory, the other attempted to delete all
|
||
files on my hard drive! (It would have worked but I had turned
|
||
off the hard drive before testing that file - whew!)
|
||
|
||
TurboCity BBS is handling this newest nonsense in three ways:
|
||
|
||
1. We will not display any uploaded files until the nightly
|
||
clean-up routine strips all comments from ZIPped files.
|
||
|
||
2. We suggest strongly that you download a file from our
|
||
selection, called STRIPZ11.ZIP. (It has been checked by
|
||
me for any damaging comments). Then run every single
|
||
ZIPped file you have or get thru that program! This
|
||
should be the very first thing you do when you get a new
|
||
ZIPped file. If you follow this then you will not have
|
||
any trouble (with this particular nonsense, anyway).
|
||
|
||
3. TurboCity will post a series of files designed to educate
|
||
one on how to use ANSI Escape Sequences in various tasks.
