         Critical Information about Lotus CCMAIL Security Upgrade

CIAC has received information from Lotus regarding a vulnerability in cc:Mail
for Windows. Under certain circumstances, the user's password can be viewed
on their local hard drive.  This vulnerability exists only in cc:Mail Windows
2.0 and 2.01.

To correct the problem, a software upgrade, cc:Mail for Windows 2.02, has
been made available.  This upgrade is contained in the file WINFIX.ZIP.
WINFIX.ZIP can be downloaded from three sources: anonymous ftp, CompuServe,
or the Lotus cc:Mail BBS.  The file is available via anonymous ftp from
ftp.ccmail.com in the /pub/windows directory.  On the anonymous ftp server,
WINFIX.ZIP is dated Feb 19 00:53 and is 279803 bytes long.

In CompuServe, perform the following commands: 

  a. Enter the Lotus forum by typing GO LOTUSC from any CompuServe prompt.
  b. Enter Section 10 when prompted for which section.
  c. From within Section 10, select "Download" and download the file
     WINFIX.ZIP.

The Lotus cc:Mail BBS is available to everyone via modem.  The telephone
number is (415) 691-0401.  Your modem setting should be: 8 data bits, No
Parity, 1 stop bit.  Once connected, go to the "File Area" by typing "F".
Select the download option and download the file WINFIX.ZIP.  On the BBS,
WINFIX.ZIP is 279803 bytes long and is dated 2/18/94 at 2:02a.

After unzipping WINFIX.ZIP, the following files are available:

ccmail.exe    628656 bytes
readme.now    1062 bytes

Your next step is to install this upgrade.  Change to the directory (which is
likely to be m:\ccmail) that contains the old version of ccmail.exe.  Rename
the old copy of ccmail.exe to ccmail.old, and then copy the new ccmail.exe to
the directory.  If cc:Mail for Windows has been installed on a network, the
system administrator only needs to change the network copy of ccmail.exe.  If
cc:Mail for Windows has been installed locally, ccmail.exe must be installed
in the proper directory of every workstation.

After installation of ccmail.exe, all users should change their password.
