The manipulation of the argument global with an unknown input leads to a numeric error vulnerability. The CWE definition for the vulnerability is CWE-189. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

KDC in MIT Kerberos 5 (krb5kdc) does not set a global variable for some krb4 message types, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted messages that trigger a NULL pointer dereference or double-free.

The bug was discovered 03/18/2008. The weakness was disclosed 03/19/2008 as confirmed advisory (CERT.org). It is possible to read the advisory at kb.cert.org. This vulnerability is known as CVE-2008-0062 since 01/03/2008. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details of the vulnerability are known, but there is no available exploit.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 67669 (Oracle Linux 3 : krb5 (ELSA-2008-0181)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 115824 (VMware Security Update (VMSA-2008-0008 and VMSA-2008-0009)).

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (41275), Tenable (67669), SecurityFocus (BID 28303†), OSVDB (43341†) and Secunia (SA29428†). The entries VDB-3721, VDB-3722, VDB-3719 and VDB-3720 are pretty similar. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
