OpenBSD 3.4/3.5/3.6 isakmpd IPsec sys/net/pfkeyv2.c heap-based overflow

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 OpenBSD 3.4/3.5/3.6 (Operating System). It has been rated as critical. This issue affects an unknown function of the file sys/net/pfkeyv2.c of the component isakmpd IPsec Handler. The manipulation with an unknown input leads to a heap-based overflow vulnerability. Using CWE to declare the problem leads to CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). Impacted is availability. The summary by CVE is:

Heap-based buffer overflow in isakmpd on OpenBSD 3.4 through 3.6 allows local users to cause a denial of service (panic) and corrupt memory via IPSEC credentials on a socket.

The bug was discovered 12/14/2004. The weakness was presented 12/15/2004 with OpenBSD Team (Website). It is possible to read the advisory at openbsd.org. The identification of this vulnerability is CVE-2004-2230 since 07/17/2005. The attack needs to approached within the local network. No form of authentication is needed for a successful exploitation. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k.

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

The vulnerability is also documented in the databases at X-Force (18486), SecurityFocus (BID 11928†), OSVDB (12400†), Secunia (SA13443†) and SecurityTracker (ID 1012511†). ftp.openbsd.org is providing further details.
