Linux Kernel 2.4.x sendmsg deadlock

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.

A vulnerability, which was classified as problematic, has been found in Linux Kernel 2.4.x (Operating System). This issue affects the function sendmsg. The manipulation with an unknown input leads to a deadlock vulnerability. Using CWE to declare the problem leads to CWE-833. The product contains multiple threads or executable segments that are waiting for each other to release a necessary lock, resulting in deadlock. Impacted is availability. The summary by CVE is:

The scm_send function in the scm layer for Linux kernel 2.4.x up to 2.4.28, and 2.6.x up to 2.6.9, allows local users to cause a denial of service (system hang) via crafted auxiliary messages that are passed to the sendmsg function, which causes a deadlock condition.

The bug was discovered 12/14/2004. The weakness was presented 12/21/2004 by Paul Starzetz with isec.pl (Website). It is possible to read the advisory at archives.neohapsis.com. The identification of this vulnerability is CVE-2004-1016 since 11/04/2004. The exploitation is known to be easy. Attacking locally is a requirement. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known.

The exploit is available at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 7 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 16303 (SUSE-SA:2004:044: kernel), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks.
