Mandrake Linux Security Update Advisory
________________________________________________________________________
Package name: packages containing zlib
Advisory ID: MDKSA-2002:023-1
Date: March 13th, 2002
Original Advisory Date: March 12th, 2002
Affected versions: 7.1, 7.2, 8.0, 8.1, Corporate Server 1.0.1
________________________________________________________________________
Problem Description:
Matthias Clasen found a security issue in zlib that, when provided with
certain input, causes zlib to free an area of memory twice. This
"double free" bug can be used to crash any programs that take untrusted
compressed input, such as web browsers, email clients, image viewing
software, etc. This vulnerability can be used to perform Denial of
Service attacks and, quite possibly, the execution of arbitrary code on
the affected system.
MandrakeSoft has published two advisories concerning this incident:
MDKSA-2002:022 - zlib
MDKSA-2002:023 - packages containing zlib
Update:
Additional package are now available. For a list of prior packages
released, please see MDKSA-2002:023. The noted packages below are in
addition to MDKSA-2002:023; no packages have been replaced.

To upgrade automatically, use MandrakeUpdate. The verification of md5
checksums and GPG signatures is performed automatically for you.
If you want to upgrade manually, download the updated package from one
of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm". A list of
FTP mirrors can be obtained from:
http://www.mandrakesecure.net/en/ftp.php
Please verify the update prior to upgrading to ensure the integrity of
the downloaded package. You can do this with the command:
rpm --checksig <filename>
All packages are signed by MandrakeSoft for security. You can obtain
the GPG public key of the Mandrake Linux Security Team from:
https://www.mandrakesecure.net/RPM-GPG-KEYS
Please be aware that sometimes it takes the mirrors a few hours to
update.
