FreeBSD/OpenBSD TCP/IP Implementation ip_input.c input validation

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 FreeBSD and OpenBSD (Operating System) (the affected version unknown) and classified as problematic. Affected by this issue is an unknown part of the file ip_input.c of the component TCP/IP Implementation. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is availability. CVE summarizes:

ip_input.c in BSD-derived TCP/IP implementations allows remote attackers to cause a denial of service (crash or hang) via crafted packets.

The weakness was released 12/30/1999 by Guido van Rooij and Joel Boutros with RISE Security (Website). The advisory is shared for download at osvdb.org. This vulnerability is handled as CVE-1999-0001. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details as well as a exploit are known.

The exploit is available at securityfocus.com. It is declared as proof-of-concept.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (338), SecurityFocus (BID 120†), OSVDB (5707†) and Vulnerability Center (SBV-2125†). Entries connected to this vulnerability are available at VDB-14040 and VDB-14248. Once again VulDB remains the best source for vulnerability data.
