CVE-2012-0255

Published: 2012-04-05 13:25:00
CVE Author: NIST National Vulnerability Database (NVD)
Summary:

The BGP implementation in bgpd in Quagga before 0.99.20.1 does not properly use message buffers for OPEN messages, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a message associated with a malformed Four-octet AS Number Capability (aka AS4 capability).

Exploitability Analysis:

This is a vulnerability exploitable with network access which means the vulnerable software is bound to the network stack and the attacker does not require local network access or local access to exploit it. Such a vulnerability is often termed “remotely exploitable”.

Exploitability Complexity:

Specialized access conditions or extenuating circumstances do not exist. The following are examples: The affected product typically requires access to a wide range of systems and users, possibly anonymous an untrusted (e.g., Internet-facing web or mail server). The affected configuration is default or ubiquitous. The attack can be performed manually and requires little skill or additional information gathering. The 'race condition' is a lazy one (i.e., it is technically a race but easily winnable).

Authentication:

Authentication is not required to access and exploit the vulnerability.

Confidentiality Impact:

There is no impact to the confidentiality of the system.

Integrity Impact:

There is no impact to the integrity of the system.

Availability Impact:

There is reduced performance or interruptions in resource availability. An example is a network-based flood attack that permits a limited number of successful connections to an Internet service.
