"Multiple vulnerabilities have been found in the Kerberos network
authentication system. The MIT Kerberos team have released an advisory
detailing these vulnerabilities, 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
(CVE-2002-0036). Mandrake Linux 9.0+ is not affected by this problem.

Vulnerabilities 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
(CVE-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
(CVE-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 (CVE-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 (CVE-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 (CVE-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
(CVE-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 (CVE-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.

Update :

The packages for Mandrake Linux 9.1 and 9.1/PPC were not GPG-signed.
This has been fixed and as a result the md5sums have changed. Thanks
to Mark Lyda for pointing this out."

"Updated kerberos packages fix a number of vulnerabilities found in MIT
Kerberos.

Kerberos is a network authentication system. The MIT Kerberos team
released an advisory describing a number of vulnerabilities that
affect the kerberos packages shipped by Red Hat.

An integer signedness error in the ASN.1 decoder before version 1.2.5
allows remote attackers to cause a denial of service via a large
unsigned data element length, which is later used as a negative value.
The Common Vulnerabilities and Exposures project has assigned the name
CVE-2002-0036 to this issue.

The Key Distribution Center (KDC) before version 1.2.5 allows remote,
authenticated, attackers to cause a denial of service (crash) on KDCs
within the same realm via a certain protocol request that :

  - causes a NULL pointer dereference (CVE-2003-0058).

  - causes the KDC to corrupt its heap (CVE-2003-0082).

A vulnerability in Kerberos before version 1.2.3 allows users from one
realm to impersonate users in other realms that have the same
inter-realm keys (CVE-2003-0059).

The MIT advisory for these issues also mentions format string
vulnerabilities in the logging routines (CVE-2003-0060). Previous
versions of the kerberos packages from Red Hat already contain fixes
for this issue.

Vulnerabilities have been found in the implementation of support for
triple-DES keys in the implementation of the Kerberos IV
authentication protocol included in MIT Kerberos (CVE-2003-0139).

Vulnerabilities have been found in the Kerberos IV authentication
protocol which allow an attacker with knowledge of a cross-realm key
that is shared with another realm to impersonate any principal in that
realm to any service in that realm. This vulnerability can only be
closed by disabling cross-realm authentication in Kerberos IV
(CVE-2003-0138).

Vulnerabilities have been found in the RPC library used by the kadmin
service in Kerberos 5. A faulty length check in the RPC library
exposes kadmind to an integer overflow which can be used to crash
kadmind (CVE-2003-0028).

All users of Kerberos are advised to upgrade to these errata packages,
which disable cross-realm authentication by default for Kerberos IV
and which contain backported patches to correct these issues."
