Vulnerability Note VU#427972

Mozilla denial of service vulnerability

Overview

Certain Mozilla products contain a denial-of-service vulnerability.

I. Description

Certain Mozilla products contain a denial-of-service vulnerability that occurs because of an infinite loop in the js_dtoa function. Mozilla Firefox versions prior to 2.0.0.1, Thunderbird prior to 1.5.0.9, and other Mozilla products may be affected.

According to Mozilla Foundation Security Advisory 2006-68:

    Keith Victor reported that if the floating point precision of the CPU was reduced (which can happen on windows by loading a plugin which creates a Direct3D device) then it is possible that js_dtoa() will not exit and instead overwrite memory. None of the most common plugins in use do this which lowers the overall impact of this vulnerability to moderate.

II. Impact

A remote unauthenticated attacker may be able to cause a denial-of-service condition.

III. Solution

Upgrade

The Mozilla Foundation has released upgrades that address this issue. See Mozilla Foundation Security Advisory 2006-68 for more information.
