Vulnerability Note VU#258423

Google Chrome multiple vulnerabilities

Overview

Google Chrome contains multiple vulnerabilities that can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

I. Description

Google Chrome stable channel versions prior to 8.0.552.237 contain multiple memory corruption vulnerabilities. These vulnerabilities include a stack corruption vulnerability in the PDF renderer component, two memory corruption vulnerabilities in the Vorbis decoder, and a video frame size error resulting in a bad memory access.

The full list of security fixes can be found in the release notes.

II. Impact

By convincing a user to view a specially crafted HTML document, PDF file, or video file, an attacker can cause the application to crash or possibly execute arbitrary code.

III. Solution

Apply an Update

Update to version 8.0.552.237 or later. In most cases, this will happen automatically.
