NetBSD up to 1.6 Telnet 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.

Summaryinfo

A vulnerability identified as problematic has been detected in NetBSD up to 1.6. This impacts an unknown function of the component Telnet. Performing a manipulation results in memory corruption. This vulnerability is reported as CVE-2005-2969. The attack is possible to be carried out remotely. No exploit exists. You should upgrade the affected component.

Detailsinfo

A vulnerability, which was classified as critical, was found in NetBSD up to 1.6 (Operating System). This affects some unknown functionality of the component Telnet. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The SSL/TLS server implementation in OpenSSL 0.9.7 before 0.9.7h and 0.9.8 before 0.9.8a, when using the SSL_OP_MSIE_SSLV2_RSA_PADDING option, disables a verification step that is required for preventing protocol version rollback attacks, which allows remote attackers to force a client and server to use a weaker protocol than needed via a man-in-the-middle attack.

The bug was discovered 10/11/2005. The weakness was disclosed 11/02/2005 with NetBSD Team (Website). The advisory is shared at ftp.netbsd.org. This vulnerability is uniquely identified as CVE-2005-2969 since 09/19/2005. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 20031 (GLSA-200510-11 : OpenSSL: SSL 2.0 protocol rollback), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gentoo Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 185030 (HP-UX Running OpenSSL Multiple Vulnerabilities (HPSBUX02174)).

Upgrading eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at netbsd.org. The best possible mitigation is suggested to be upgrading to the latest version. 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 (35287), Tenable (20031), SecurityFocus (BID 24799†), OSVDB (19919†) and Secunia (SA26893†). The entries VDB-1786, VDB-1803, VDB-1860 and VDB-1858 are pretty similar. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
