                    Mandrake Linux Security Update Advisory
    ________________________________________________________________________

    Package name: krb5
    Advisory ID: MDKSA-2003:043
    Date: April 1st, 2003

    Affected versions: 8.2, 9.0, 9.1, Corporate Server 2.1,
                            Multi Network Firewall 8.2
    ________________________________________________________________________

    Problem Description:

     Multiple vulnerabilties have been found in the Kerberos network
     authentication system. The MIT Kerberos team have released an
     advisory detailing these vulnerabilties, a description of which
     follows.
     
     An integer signedness error in the ASN.1 decoder before version 1.2.5
     allows remote attackers to cause a crash of the server via a large
     unsigned data element length, which is later used as a negative
     value (CAN-2002-0036). Mandrake Linux 9.0+ is not affected by
     this problem.
     
     Vulnerabilties have been found in the RPC library used by the kadmin
     service. A faulty length check in the RPC library exposes kadmind to
     an integer overflow which can be used to crash kadmind (CAN-2003-0028).
     
     The KDC (Key Distribution Center) before version 1.2.5 allows remote,
     authenticated attackers to cause a crash on KDCs within the same realm
     using a certain protocol that causes a null dereference
     (CAN-2003-0058). Mandrake Linux 9.0+ is not affected by this problem.
     
     Users from one realm can impersonate users in other realms that have
     the same inter-realm keys due to a vulnerability in Kerberos 1.2.3
     and earlier (CAN-2003-0059). Mandrake Linux 9.0+ is not affected by
     this problem.
     
     The KDC allows remote, authenticated users to cause a crash on KDCs
     within the same realm using a certain protocol request that causes an
     out-of-bounds read of an array (CAN-2003-0072).
     
     The KDC allows remote, authenticated users to cause a crash on KDCs
     within the same realm using a certain protocol request that causes the
     KDC to corrupt its heap (CAN-2003-0082).
     
     Vulnerabilities have been discovered in the Kerberos IV authentication
     protocol which allow an attacker with knowledge of a cross-realm key,
     which is shared in another realm, to impersonate a principle in that
     realm to any service in that realm. This vulnerability can only
     be closed by disabling cross-realm authentication in Kerberos IV
     (CAN-2003-0138).
     
     Vulnerabilities have been discovered in the support for triple-DES
     keys in the Kerberos IV authentication protocol which is included
     in MIT Kerberos (CAN-2003-0139).
     
     MandrakeSoft encourages all users to upgrade to these updated packages
     immediately which contain patches to correct all of the previously
     noted vulnerabilities. These packages also disable Kerberos IV
     cross-realm authentication by default.

    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.
