NetBSD up to 1.6.2 compat denial of service

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 NetBSD up to 1.6.2 (Operating System) and classified as problematic. This issue affects an unknown part of the component compat. The manipulation with an unknown input leads to a denial of service vulnerability. Using CWE to declare the problem leads to CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. Impacted is availability. The summary by CVE is:

Multiple syscalls in the compat subsystem for NetBSD before 2.0 allow local users to cause a denial of service (kernel crash) via a large signal number to (1) xxx_sys_kill, (2) xxx_sys_sigaction, and possibly other translation functions.

The bug was discovered 12/17/2004. The weakness was disclosed 12/18/2004 by Evgeny Demidov with GLEG Ltd. (Website). It is possible to read the advisory at gleg.net. The identification of this vulnerability is CVE-2004-1323 since 01/06/2005. The attack needs to be done within the local network. No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available.

After before and not just, there has been an exploit disclosed. It is declared as proof-of-concept.

Upgrading to version 2.0 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at ftp.NetBSD.org. The best possible mitigation is suggested to be patching the affected component.
