Detailsinfo

A vulnerability was found in OpenBSD 2.8 (Operating System). It has been rated as very critical. This issue affects an unknown part of the component IPsec Authentication Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in IPSEC authentication mechanism for OpenBSD 2.8 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a malformed Authentication header (AH) IPv4 option.

The bug was discovered 02/20/2001. The weakness was shared 03/02/2001 by Jun-ichiro itojun Hagino as confirmed advisory (Website). The advisory is shared at openbsd.org. The identification of this vulnerability is CVE-2001-0284. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 05/29/2018).

The vulnerability was handled as a non-public zero-day exploit for at least 10 days. During that time the estimated underground price was around $25k-$100k.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (6492) and OSVDB (6026†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
