Package name:           zlib
Advisory ID:            MDKSA-2003:033
Date:                   March 18th, 2003

Affected versions:      7.2, 8.0, 8.1, 8.2, 9.0, Corporate Server 2.1,
                        Multi Network Firewall 8.2,

Problem Description:

 Richard Kettlewell discovered a buffer overflow vulnerability in the 
 zlib library's gzprintf() function.  This can be used by attackers 
 to cause a denial of service or possibly even the execution of 
 arbitrary code.  Our thanks to the OpenPKG team for providing a patch
 which adds the necessary configure script checks to always use the
 secure vsnprintf(3) and snprintf(3) functions, and which additionally
 adjusts the code to correctly take into account the return value of
 vsnprintf(3) and snprintf(3).

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.
