Detailsinfo

A vulnerability was found in KTH Kerberos 0.5.1/1.2.1/5-1.2.6 and classified as very critical. Affected by this issue is the function kadm_ser_in of the component kadmind4. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The kadm_ser_in function in (1) the Kerberos v4compatibility administration daemon (kadmind4) in the MIT Kerberos 5 (krb5) krb5-1.2.6 and earlier, (2) kadmind in KTH Kerberos 4 (eBones) before 1.2.1, and (3) kadmind in KTH Kerberos 5 (Heimdal) before 0.5.1 when compiled with Kerberos 4 support, does not properly verify the length field of a request, which allows remote attackers to execute arbitrary code via a buffer overflow attack.

The weakness was published 11/04/2002 by Sam Hartman as confirmed advisory (CERT.org). The advisory is available at cert.org. This vulnerability is handled as CVE-2002-1235. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 10/27/2024).

The vulnerability scanner Nessus provides a plugin with the ID 15020 (Debian DSA-183-1 : krb5 - buffer overflow), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 1894. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 1586.

The vulnerability is also documented in the databases at X-Force (10430), Tenable (15020), SecurityFocus (BID 6024†) and Vulnerability Center (SBV-6349†). If you want to get best quality of vulnerability data, you may have to visit VulDB.
