Severity:	normal
Title:	Mozilla Firefox: Potential remote code execution
Date:	05/06/2006
Bugs:	#131138
ID:	200605-06

Synopsis

The Mozilla Firefox 1.5 line is vulnerable to a buffer overflow in the JavaScript extension which may in theory lead to remote execution of arbitrary code.

Background

Mozilla Firefox is the next-generation web browser from the Mozilla project.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-client/mozilla-firefox	< 1.5.0.3	>= 1.5.0.3	All supported architectures
www-client/mozilla-firefox-bin	< 1.5.0.3	>= 1.5.0.3	All supported architectures

Description

Martijn Wargers and Nick Mott discovered a vulnerability when rendering malformed JavaScript content. The Mozilla Firefox 1.0 line is not affected.

Impact

If JavaScript is enabled, by tricking a user into visiting a malicious web page which would send a specially crafted HTML script that contains references to deleted objects with the "designMode" property enabled, an attacker can crash the web browser and in theory manage to execute arbitrary code with the rights of the user running the browser.

Workaround

There is no known workaround at this time.

Resolution

All Mozilla Firefox 1.5 users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-1.5.0.3"

All Mozilla Firefox 1.5 binary users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-1.5.0.3"
