Detailsinfo

A vulnerability classified as problematic has been found in NetBSD and OpenBSD (Operating System) (affected version unknown). This affects an unknown functionality of the component IPv4 Packet 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:

OpenBSD 3.4 and NetBSD 1.6 and 1.6.1 allow remote attackers to cause a denial of service (crash) by sending an IPv6 packet with a small MTU to a listening port and then issuing a TCP connect to that port.

The bug was discovered 02/01/2004. The weakness was released 02/04/2004 (Website). The advisory is shared at marc.theaimsgroup.com. This vulnerability is uniquely identified as CVE-2004-0257. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 3 days. During that time the estimated underground price was around $0-$5k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (15044), SecurityFocus (BID 9577†), OSVDB (3825†) and Secunia (SA10801†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
