Impact by CVSS Score
  • ID: CVE-2000-0456
Summary:

NetBSD 1.4.2 and earlier allows local users to cause a denial of service by repeatedly running certain system calls in the kernel which do not yield the CPU, aka "cpu-hog".

Exploitability Analysis: Local

A vulnerability exploitable with only local access requires the attacker to have either physical access to the vulnerable system or a local (shell) account. Examples of locally exploitable vulnerabilities are peripheral attacks such as Firewire/USB DMA attacks, and local privilege escalations (e.g., sudo).

Exploitability Complexity: Low

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: None

Authentication is not required to access and exploit the vulnerability.

Confidentiality Impact: None

There is no impact to the confidentiality of the system.

Integrity Impact: None

There is no impact to the integrity of the system.

Availability Impact: Partial

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.
