Title:	Mozilla Suite, Mozilla Firefox: Multiple vulnerabilities
Date:	09/18/2005
Bugs:	#105396
ID:	200509-11

Synopsis

Mozilla Suite and Firefox are vulnerable to multiple issues, including some that might be exploited to execute arbitrary code.

Background

The Mozilla Suite is a popular all-in-one web browser that includes a mail and news reader. Mozilla Firefox is the next-generation browser from the Mozilla project. Gecko is the layout engine used in both products.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-client/mozilla-firefox	< 1.0.7-r2	>= 1.0.7-r2	All supported architectures
www-client/mozilla	< 1.7.12-r2	>= 1.7.12-r2	All supported architectures
www-client/mozilla-firefox-bin	< 1.0.7	>= 1.0.7	All supported architectures
www-client/mozilla-bin	< 1.7.12	>= 1.7.12	All supported architectures
net-libs/gecko-sdk	< 1.7.12	>= 1.7.12	All supported architectures

Description

The Mozilla Suite and Firefox are both vulnerable to the following issues:

Tom Ferris reported a heap overflow in IDN-enabled browsers with malicious Host: headers (CAN-2005-2871).
"jackerror" discovered a heap overrun in XBM image processing (CAN-2005-2701).
Mats Palmgren reported a potentially exploitable stack corruption using specific Unicode sequences (CAN-2005-2702).
Georgi Guninski discovered an integer overflow in the JavaScript engine (CAN-2005-2705)
Other issues ranging from DOM object spoofing to request header spoofing were also found and fixed in the latest versions (CAN-2005-2703, CAN-2005-2704, CAN-2005-2706, CAN-2005-2707).

The Gecko engine in itself is also affected by some of these issues and has been updated as well.

Impact

A remote attacker could setup a malicious site and entice a victim to visit it, potentially resulting in arbitrary code execution with the victim's privileges or facilitated spoofing of known websites.

Workaround

There is no known workaround for all the issues.

Resolution

All Mozilla Firefox users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-1.0.7-r2"

All Mozilla Suite users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-1.7.12-r2"

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


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-1.0.7"

All Mozilla Suite binary users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-bin-1.7.12"

All Gecko library users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-libs/gecko-sdk-1.7.12"
