CVE-2015-6788

Description

A flaw was found in the chromium-browser extensions subsystem. A remote attacker could exploit this vulnerability by convincing a user to install or run a crafted browser extension. This triggers a type confusion condition, where the software misinterprets data types in memory, potentially allowing the attacker to execute arbitrary code or cause an application crash resulting in a Denial of Service (DoS).

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).

Understanding the Weakness (CWE)

CWE-843

Other

Technical Impact: Varies by Context

When the product accesses the resource using an incompatible type, this could trigger logical errors because the resource does not have expected properties.

Availability,Integrity,Confidentiality

Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart

If a memory buffer is accessed using an incompatible type, and the allocated buffer is smaller than the type that the code is attempting to access, then an attacker could read or write memory outside the bounds of the buffer, leading to a crash or possibly code execution.
