Detailsinfo

A vulnerability was found in MIT Kerberos 5-1.2.1/5-1.2.2/5-1.2.3/5-1.2.4 (Network Authentication Software). It has been classified as problematic. This affects an unknown function of the component Key Distribution Center. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

MIT Kerberos V5 Key Distribution Center (KDC) before 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 dereference.

The bug was discovered 09/16/2002. The weakness was shared 02/19/2003 as confirmed advisory (CERT.org). It is possible to read the advisory at kb.cert.org. This vulnerability is uniquely identified as CVE-2003-0058. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 156 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 14027 (Mandrake Linux Security Advisory : krb5 (MDKSA-2003:043-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 38371 (Red Hat Kerberos Multiple Vulnerabilities).

Upgrading to version 1.2.5 eliminates this vulnerability. A possible mitigation has been published 2 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (10099), Tenable (14027), SecurityFocus (BID 6683†), OSVDB (4874†) and Vulnerability Center (SBV-6752†).
