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.
