FreeBSD up to 5.2 TCP Queue Sequence 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, which was classified as critical, was found in FreeBSD up to 5.2 (Operating System). This affects an unknown code of the component TCP Queue Sequence Handler. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. The summary by CVE is:

FreeBSD 5.1 and earlier, and Mac OS X before 10.3.4, allows remote attackers to cause a denial of service (resource exhaustion of memory buffers and system crash) via a large number of out-of-sequence TCP packets, which prevents the operating system from creating new connections.

The bug was discovered 01/22/2004. The weakness was presented 03/03/2004 by Alexander Cuttergo with iDEFENSE (Website). It is possible to read the advisory at ftp.FreeBSD.org. This vulnerability is uniquely identified as CVE-2004-0171. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but an exploit is available.

The exploit is shared for download at hping.org. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 41 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 12257 (Mac OS X < 10.3.4 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks and running in the context c.

Applying a patch is able to eliminate this problem. The bugfix is ready for download at ftp.FreeBSD.org.

The vulnerability is also documented in the databases at X-Force (15369), Tenable (12257), SecurityFocus (BID 9792†), OSVDB (4124†) and Secunia (SA11023†). Further details are available at ftp.FreeBSD.org. See VDB-682, VDB-680, VDB-678 and VDB-679 for similar entries. Be aware that VulDB is the high quality source for vulnerability data.
