                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           ispell
Date:                   June 20th, 2001
Advisory ID:            MDKSA-2001:058

Affected versions:      7.1, 7.2, 8.0, Corporate Server 1.0.1
________________________________________________________________________

Problem Description:

 The ispell program uses mktemp() to open temporary files.  This makes
 it vulnerable to symlink attacks.  The program now has a patch from
 OpenBSD applied that uses mkstemp() instead, and switches gets() to
 fgets() for dealing with user input.

To upgrade automatically, use MandrakeUpdate.

If you want to upgrade manually, download the updated package from one
of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm".

You can download the updates directly from one of the mirror sites
listed at:

   http://www.linux-mandrake.com/en/ftp.php3.

Updated packages are available in the "updates/[ver]/RPMS/" directory.
For example, if you are looking for an updated RPM package for
Mandrake Linux 8.0, look for it in "updates/8.0/RPMS/".  Updated source
RPMs are available as well, but you generally do not need to download
them.

Please be aware that sometimes it takes the mirrors a few hours to
update.
