CVE-2010-5331

Description

A vulnerability was found in the Linux kernel where a range check issue in drivers/gpu/drm/radeon/atombios.c could cause an off by one buffer overflow problem. It has been determined that this flaw is cannot be influenced by an attacker.

Statement

Red Hat will not be fixing this flaw as it has been analyzed as not affecting any version of Linux.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.

Red Hat CVSS v3 Score Explanation

AV has changed because the graphics card driver is not network accessible, PR has changed as there is a requirement to have an account C: I: A: has changed as there the buggy code is not attacker influenced.

Understanding the Weakness (CWE)

Availability

Technical Impact: DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Instability

This weakness will generally lead to undefined behavior and therefore crashes. In the case of overflows involving loop index variables, the likelihood of infinite loops is also high.

Integrity

Technical Impact: Modify Memory

If the value in question is important to data (as opposed to flow), simple data corruption has occurred. Also, if the wrap around results in other conditions such as buffer overflows, further memory corruption may occur.

Confidentiality,Availability,Access Control

Technical Impact: Execute Unauthorized Code or Commands; Bypass Protection Mechanism

This weakness can sometimes trigger buffer overflows which can be used to execute arbitrary code. This is usually outside the scope of a program's implicit security policy.
