Mozilla fails to properly handle simultaneous XPCOM events

Vulnerability Note VU#239124

Original Release Date: 2006-07-27 | Last Revised: 2007-02-09

Overview

Mozilla products are vulnerable to memory corruption via simultaneous XPCOM events. This may allow a remote attacker to execute arbitrary code on a vulnerable system.

Description

XPCOM

XPCOM is a cross-platform component object model similar to Microsoft COM or CORBA. XPCOM provides the following features to software developers:

    • Component management
    • File abstraction
    • Object message passing
    • Memory Management
The problem

XPCOM events that occur simultaneously can trigger the use of a deleted timer object, which can cause memory corruption.

Impact

A remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. The attacker could also cause the vulnerable application to crash.
