A stack buffer overflow in the implementation of the Kerberos v4 compatibility administration daemon (kadmind4) in the krb5 package can be exploited to gain unauthorized root access to a KDC host. Authentication to the daemon is not required to successfully perform the attack and according to MIT at least one exploit is known to exist. kadmind4 is used only by sites that require compatibility with legacy administrative clients, and sites that do not have these needs are likely not using kadmind4 and are not affected. MandrakeSoft encourages all users who use Kerberos to upgrade to these packages immediately.

Problem Description:

 A stack buffer overflow in the implementation of the Kerberos v4
 compatibility administration daemon (kadmind4) in the krb5 package can
 be exploited to gain unauthorized root access to a KDC host.
 Authentication to the daemon is not required to successfully perform
 the attack and according to MIT at least one exploit is known to exist.
 kadmind4 is used only by sites that require compatibility with legacy
 administrative clients, and sites that do not have these needs are
 likely not using kadmind4 and are not affected.

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.

You can view other update advisories for Mandrake Linux at:
