1. Summary:

An updated firefox package that fixes several security bugs is now
available for Red Hat Enterprise Linux 4.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

Mozilla Firefox is an open source Web browser.

A bug was found in the way Firefox processes XBM image files. If a user
views a specially crafted XBM file, it becomes possible to execute
arbitrary code as the user running Firefox. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2005-2701 to
this issue.

A bug was found in the way Firefox processes certain Unicode
sequences. It may be possible to execute arbitrary code as the user running
Firefox if the user views a specially crafted Unicode sequence. (CAN-2005-2702)

A bug was found in the way Firefox makes XMLHttp requests. It is possible
that a malicious web page could leverage this flaw to exploit other proxy
or server flaws from the victim's machine. It is also possible that this
flaw could be leveraged to send XMLHttp requests to hosts other than the
originator; the default behavior of the browser is to disallow this.
(CAN-2005-2703)

A bug was found in the way Firefox implemented its XBL interface. It may be
possible for a malicious web page to create an XBL binding in such a way
that would allow arbitrary JavaScript execution with chrome permissions.
Please note that in Firefox 1.0.6 this issue is not directly exploitable
and will need to leverage other unknown exploits. (CAN-2005-2704)

An integer overflow bug was found in Firefox's JavaScript engine. Under
favorable conditions, it may be possible for a malicious web page to
execute arbitrary code as the user running Firefox. (CAN-2005-2705)

A bug was found in the way Firefox displays about: pages. It is possible
for a malicious web page to open an about: page, such as about:mozilla, in
such a way that it becomes possible to execute JavaScript with chrome
privileges. (CAN-2005-2706)

A bug was found in the way Firefox opens new windows. It is possible for a
malicious web site to construct a new window without any user interface
components, such as the address bar and the status bar. This window could
then be used to mislead the user for malicious purposes. (CAN-2005-2707)

A bug was found in the way Firefox processes URLs passed to it on the
command line. If a user passes a malformed URL to Firefox, such as clicking
on a link in an instant messaging program, it is possible to execute
arbitrary commands as the user running Firefox. (CAN-2005-2968)

Users of Firefox are advised to upgrade to this updated package that
contains Firefox version 1.0.7 and is not vulnerable to these issues.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/):

168527 - CAN-2005-2701 Multiple Firefox issues (CAN-2005-2702, CAN-2005-2703, CAN-2005-2704, CAN-2005-2705, CAN-2005-2706, CAN-2005-2707)
