Linux Kernel 2.4.x Packet Fragmentation 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 has been found in Linux Kernel 2.4.x (Operating System) and classified as critical. Affected by this vulnerability is an unknown code block of the component Packet Fragmentation Handler. The manipulation with an unknown input leads to a denial of service vulnerability. The CWE definition for the vulnerability is CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. As an impact it is known to affect availability. The summary by CVE is:

HP-UX B.11.00, B.11.04, B.11.11, and B.11.23 allows remote attackers to cause a denial of service via a "Rose Attack" that involves sending a subset of small IP fragments that do not form a complete, larger packet.

The bug was discovered 12/09/2005. The weakness was shared 10/01/2004 by Gandalf The White (DiGiT) (Website). It is possible to read the advisory at digital.net. This vulnerability is known as CVE-2005-4316 since 12/17/2005. The attack can be launched remotely. The exploitation doesn't need any form of authentication.
