NetBSD up to 2.0 ftpd 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, which was classified as problematic, was found in NetBSD up to 2.0 (Operating System). This affects an unknown code of the component ftpd. 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:

Multiple signal handler race conditions in lukemftpd (aka tnftpd before 20040810) allow remote authenticated attackers to cause a denial of service or execute arbitrary code.

The weakness was published 08/18/2004 by Przemyslaw Frasunek with NetBSD Team (Website). It is possible to read the advisory at ftp.NetBSD.org. This vulnerability is uniquely identified as CVE-2004-0794 since 08/17/2004. Attacking locally is a requirement. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 15388 (Debian DSA-551-1 : lukemftpd - incorrect internal variable handling), 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.

Applying a patch is able to eliminate this problem. The bugfix is ready for download at ftp.NetBSD.org. 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 (17020), Tenable (15388), SecurityFocus (BID 10967†), OSVDB (8994†) and Secunia (SA12318†). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
