OpenSSL 0.9.7 Kerberos memory corruption

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in OpenSSL 0.9.7 (Network Encryption Software). It has been declared as critical. Affected by this vulnerability is some unknown functionality of the component Kerberos. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in OpenSSL 0.9.7 before 0.9.7-beta3, with Kerberos enabled, allows attackers to execute arbitrary code via a long master key.

The issue has been introduced in 12/31/2002. The weakness was released 08/12/2002 by DiGiT as confirmed advisory (CERT.org). The advisory is shared at cert.org. This vulnerability is known as CVE-2002-0657. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 17752 (OpenSSL < 0.9.7-beta3 Buffer Overflow), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Web Servers and running in the context r.

Upgrading to version 0.9.7 eliminates this vulnerability. A possible mitigation has been published 6 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (9715), Tenable (17752), SecurityFocus (BID 5361†) and Vulnerability Center (SBV-1209†). Entries connected to this vulnerability are available at VDB-18603, VDB-18600 and VDB-18599. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
