Mozilla DHTML memory corruption vulnerabilities

Vulnerability Note VU#350262

Original Release Date: 2006-04-17 | Last Revised: 2006-05-17

Overview

Mozilla products contain multiple unspecified vulnerabilities in the way they handle DHTML. These vulnerabilities may allow a remote attacker to execute arbitrary code or cause a denial-of-service condition.

Description

Mozilla products fail to properly handle DHTML. This may allow memory to be corrupted in a way that could allow an attacker to execute arbitrary code. For more information, please refer to Mozilla Foundation Security Advisory 2006-20.

Note that some attack vectors for these vulnerabilities require JavaScript, which is enabled by default in the Firefox and Mozilla web browsers but not in Mozilla's mail client or Thunderbird. Exploitation may occur by accessing a specially crafted web page with Firefox. If JavaScript is enabled within Mozilla's mail client or Thunderbird, exploitation is possible by opening a specially crafted email.

Impact

A remote, unauthenticated attacker may be able to execute arbitrary code or cause the affected Mozilla product to crash.

Solution

Upgrade
This issue is fixed in Firefox 1.5.0.2, Thunderbird 1.5.0.2, and SeaMonkey 1.0.1.

Disable JavaScript


For instructions on how to disable JavaScript in Firefox, please refer to the Firefox section of the Securing Your Web Browser document.
